First, yes this is hard, but it's important that you get him to sleep in his own bed! You must sleep! That is most important since if you are not getting enough sleep you are not going to be as healthy. Also, it's important that you and your mate have private time together, whether it's for sex or cuddling or hugging - all of that is part of your intimate life and it's important to retain that (it's hard to get in the mood with a toddler in the bed with you :) It seems that he's nursing so that he has private cuddling time with you and does not have to do with food.- and can you blame him? You are what he is looking forward to seeing all day long - so continue the cuddling and the hugging that comes with nursing, and just remove the nursing part... read books while he's on your lap, hold him and sing him songs, ask him about his day all while in the same cuddling position - just not including the nursing. If he drinks from a sippy cup or bottle at daycare, then he can do the same at home - but know that he is not nursing for milk - that is his private, quiet, sweet mommy time. This method will work, but it means that you have to stick to it - let him know that you love him but that he has to drink from his bottle and that you want to read him a book or tell him a story while he drinks his milk (if he is hungry). To get him to sleep in his own room, that's trickier - on the weekends get him to nap in his own room and when you are ready to tell him about the new baby, turn him into a "Big Brother" who is such a big boy now that he won't need to sleep with mom and dad anymore. And if you haven't already done so, let him pick out his own sheets for his bed and a new best buddy to sleep with - and make it fun, not scary... you'll do fine, ask close friends for support during this transition, and stay calm and positive. This will soon be only a memory and you will be able to focus on the new arrival! Good luck! (I have a few more tips in my book: www.coolyourepregnant.com that might help)
