lol my mom was the same way and she still tell me i doing everything wrong i a mad mom cause i let my kid cry it an endless battle you will never be as good as your parents so just ingore her babbling crap

I think they are all just scared of what is going to happen. Just try not to think about it right now, and just prove them all wrong when baby gets here. And just be the best mom you can be.
And I know what you are feeling, right now I dont have anything to do either, and no reason to get up in the day, and plus my sleeping habits are really messed up. But that doesnt mean I wont be a good mom, I will just have to adjust my schedule when baby comes. And I am willing to do that.
So when that baby comes, prove them all wrong, and try your best, and love and care for that baby as best you can. Im sure yourll do just fine. Then you can say, told ya so. LOL Good luck.

Age should not factor into the situation. There are women out there who are not mature enough to have a child and they are in their 30 and 40's. If you feel you are prepared and have the help and support you need (at any age you need a good supprt system) then by all means, you can be a great mom. Good luck and if you need to talk, let me know.

Getting your rest now is important too! I consider myself lucky because I can sleep when I need to too. Remind your mom that your body needs all the rest it can get now and to not sleep when you can isn't the best idea.

Try not to get too upset with your mom, you are going to need her more than you can ever imagin. It is normal for you to want to sleep a lot. Are you still in school? Finish as much of it as you can now before the baby comes.

Remind your mum how taxing pregnancy is on the body & that your body will release all kinds of hormones like adrenaline and ocytocin when the bub is born to assist in you naturally stepping up, and taking care of your babe in the way he / she will need.

You could do this maybe by sugesting that she may have forgotton / that studies have progressed since she was pregnant and it is now known that it is best to rest your body and mind as much as you can during this time, that it is normal for your sleep patters to be out of wack etc...

Give her an update pregnancy book to read and tell her once she has reinformed her self with proffessional advice you will be more open to her input and if she chooses not to modernise her facts you will find it difficult to respect her input as far as your sleep goes.
