My son is 20 months now. When this started happening. I started going in his room as soon as he woke up...getting him out of the crib and out of his room. So he could not doze off later. This worked well because come 12-1pm, he was tired enough not to put up a fight for nap time. He wakes and goes to bed about the same time as yours.
hope that helps:)

You're right to think she misses her daddy and wants to stay up for him. Perhaps there's a way for him to make some time for her that is not at nap time? What I found out from my two kids is that syncing up their bedtime with sun works best. Somehow they take cues from sun/dark outside. E.g. each time clock changed they were getting up and going to bed at a later or earlier time (depending on the change) a week or two BEFORE the actual change. It's just that sun was coming up sooner or later and they followed it. It's unfortunate that you can't put her to bed at sundown but perhaps there's a way for a sitter to put her to bed at her place and then you just carry her to car and carry her upstairs at home? I'm sorry I don't have any better advice.

My son has always been a good sleeper but I think a lot of that has to do with a very consistent schedule. He goes to bed between 7:30-8pm every night and wakes up between 6:30-7am. I will let him sleep until 7:30am if need be but if he isn't up by then, I wake him up...Ive only had to do this one time. He goes to daycare daily and I really try to stick with their eating and sleeping schedule and it works. He goes down for a nap between 11:30-1pm (depending on what we are doing) and wakes up 90 minutes to 2 hours later, depending on what we did that morning...more activity, the longer the nap... If there is a change in the schedule, or someone is here visiting, it is hard for him to go down for a nap but with a lot of "support", he does fall asleep. I try not to change up his schedule too much but there are things that we want to do that do interfere with his nap time, like today we are meeting a group of friends at noon. He will mostly nap in the car for about 40 minutes and then go to bed maybe 15 minutes early. Just depends. But I do like for us to have activities scheduled on the weekend and unfornutately a lot of things seem to happen between noon and 3pm... Good luck!! Oh and my son just turned 2 last weekend.

Thanks guys! There's been alot of helpful advice in here!

We are trying to switch her naptime to 4, so she sleeps til 6. That means completley changing her eating schedule, it used to be 12 and 5, but now we are trying 1 and 6. That way she get's to see Daddy for about half hour, forty five minutes, when he get's home between jobs. He has been the one layng her down. Plus, by napping until 6, she can stay up until 930 and that gives half an hour to an hour of Daddy time after he's done his second job.

It's not ideal, but it's the only way she gets to see Daddy some days.

On day's with a sitter, she still isn't napping. She absolutley refuses to nap anywhere but home. Plus, in the car she only sleeps as long as thier is motion, the second you stop for more then 20 seconds shes up. Often she half wakes up at stop lights then goes back to sleep when the light goes green!

But once again, thanks for the tons of super advice!

I like the suggestion of quiet time. My older boys were in preschool starting at age two, naptime was required. The children who didn't sleep were given soft books or puppets or other quiet things to play with on their cot. When the children were older like 4 or 5 the non-nappers were given coloring books and things, but they still had to stay on their cot and "rest" quietly.
my boys were always good nappers but they also woke early, like on weekdays and between 7-8:00 an weekends. I definitely think at 19 months a rest period is needed, even if it is just cuddled up in bed with you and some books.

My daugther will be 18 months old the end of this month and we are struggling with this too. Although she still desperately needs her naps, she will only sleep for 20 mins tops! She is very crabby without them but we cant seem to et back into the swing of things. Im blaming it on her incisors coming in so I sure hope her normal naps come back once her teeth finish coming in!

Your daughter might actually be taking a 'nap' when she goes back to sleep in the morning (before she's gotten out of her crib). Have you tried getting her up before she falls asleep in the morning (after she's played with her stuffies, of course!)? She might be more likely to be tired and ready for a nap later if she gets up earlier.

I would look into what sitter is doing to facilitate a nap. A good sitter should be able to put her into nap mode by reading books quietly or taking her out in a stroller or playing a video she likes ... I'm happy to hear things are better

I think it depends on the child. I have 3.... My oldest 2 had a moning nap and an afternoon nap until somewhere between 15-18 months and then it was down to one nap. My LO needs 2 naps but does not nap well so I'm lucky when I get one true nap. My older sons were in reschool from age 2-5. The rule there was everyone laid down for a nap. As the kids out grew naps they were to lay on thier cot quietly, in the 2yr old room they were allowed to play with a stuffed toy, in the 3 yr old room they could have books, in the pre-k room they could lay or sit quietly with crayons and paper or a book. My middle is in 2nd grade and on occassion he still needs a nap!

My son just stopped taking them one day so in its place we have "quite time" where he either sits in the room and watches a movie or we sit together in a chair and relax for an hour or so. It gets us both a chance to recharge and come out happy on the other end.

As of right now she doesn't have naps unless we are at home for her nap time. She doesn't sleep at the sitters, and the sitter says she has no problems with crankiness. She doesn't nap if we are out, minus falling asleep in the car for maybe 15 minutes.

The owly moods seem to have gone as well. She is up from 10am until 8-9pm about five days a week, and we no longer really have any issues outside the usual attitude. She is 21 months.

But when we are at home, if I don't work and we don't have errands, I lay her down and she goes to sleep easy peasy for about two hours.

It seems to be working....but soon I want to introduce the toddler bed, and that may just destroy everything lol.
