I introduced the bottle at about 10 days, and worked with it when she wasn't TOO hungry- and my DH fed her with it as well so she got used to it. Now I nurse when we are together, and we use expressed breast milk (EBM) when we are apart. She is not picky at all now- she will take breast or bottle, from about anyone! (She loves her milk!)
I was lucky enough to get 12 weeks maternity leave, but I wouldn't pass up the physical closeness we get by nursing for anything! Even those first 6 weeks babies love the skin to skin contact and soothing feeling of being so close and hearing your heart beat and listening to you breathing... Plus, it's so much easier to put baby right to the breast, rather than express, feed, and then clean up all the stuff.
That being said, I know many moms who pump exclusively so that dad can help feed right from the get-go, and they do just fine (and so do the babies!). You've made the right choice by feeding EBM, and however your child gets it will be just fine.
I know there's a group on here called "pump mom's" or something like that- I'm sure you'll get awesome advice from them!!

PS- I know there's tons of other reasons to not "breast"feed- besides letting dad share the work load. That was just the example I threw out there.
And to address your concern directly, I think that if you introduce a bottle after the first week or so, it won't take too much time for him to adjust between breast and bottle. They're very smart, adaptable little beings!

MsH has some great points. I breastfeed and introduced the bottle around 2-3 weeks so that my husband and others could feed her if I needed to be away or if I just wanted a break. She took to it well and now has no problem with taking milk from a bottle or the breast. I'd say just introduce the bottle early and see how it goes.

Because I was so sick after my c-section, my daughter got a bottle her first day. I then switched her to nursing after that but had to supplement with a bottle until she was a month old. I then went to only breastfeeding, but on occassion I have to give her a bottle and she has no problem with it.

After a few sucks on the bottle, she gets use to the nipple and downs it in no time.

If you can, definately BF while on leave and then give him a bottle during the day and BF while you are with him in the evenings. Many moms do this and it works out just fine.

Thanks! Any suggestions on good bottles? I know that he will pick the one he likes but we have no clue as to which ones to try out. We are also looking for a good pump. I have heard about the medela anything any better?

I love my medela advanced in style pump. It's the double electric pump and it works amazingly well. As for bottles, we use Dr. Brown's. They have this great vent system to help with gas. Our little girl loves them. They have some tiny parts to clean, but you can put everything in a dishwasher if you have one.

I love my Medela Pump in Style and the Playtex Dropins bottles. My 3 babies all switched back and forth breast to bottleto breast, no problem. Best wishes!

I agree with the others - babies are adaptable! My doctor told us we could introduce a bottle at two weeks when BF was well established. My son is 5 weeks old now and has no issues switching back and forth, even after he had his frenulum snipped for a tongue tie! I let my DH feed him, though, so he doesn't think the bottle comes from mom.

Most babies are pretty resilient and will take both. I always breastfed, but we started having my husband feed bottles every now and again. And supposedly, that's what can cause confusion, if the MOM does both. So after the babe get the right latch and really figures out breastfeeding (at least 2-3 weeks) I'd try having someone else give the babe a bottle while you go express every once in awhile.

my fave bottle if you are going to switch between the breast and bottle is the nuck orthodonic, its similar to the breast.

One piece of bottle advice: don't buy a ton of the same bottle...your baby may not like the brand you expect. My baby hated a few different ones and the only that have worked for me are the Playtex drop ins and the Nuk (agreeing with Wannabeeemom)-- you can also buy Nuk pacifiers and that's the only binky my baby will even kind of take (not that I can get him to take it more than 2 minutes-LOL).
