My son will be one tomorrow, and I have some concerns?

Cold turkey is absolutely the best way to get rid of the bottles...but you need to get them out of the house so that no one is tempted to give him one when he cries for a bit...just give him his milk, juice, and water in the sippy, if he's thirstly he'll drink it...no child will go without something to drink just because of the cup....our daughter also threw her cup at first, but i refused to give in and she took to the cup after she realized that it was the cup or nothing...she was about 8 months old...your son may pitch a fit at first but after a few days it'll all be fine (P.S. if you don't wean him now it becomes much harder later on both you and him so why put him or yourself through that)...about your sons weight...if I remember correctly our daughter was 24 lbs and 29 inches at her last checkup at 18 months and they told me she was doing great and right at normal...22 isn't bad for a one year old...I think your WIC nutrionist should go back to school...(I've seen some post on here babies that are 6 months old and weight 20 lbs so I think you're doing a good job)..Oh and also about the cups...soft topped cups are great at first but be careful when he gets a little older because he'll learn that he can turn it upside down and push down and all the liquid will come out (our daughter learned this shortly before she turned 18 months so I had to take all her Nuby cups away to keep her from making a mess every time she had a cup)...About his sleeping, does he take a nap later in the evening say around 7 or 8...our daughter started waking back up after sleeping so well for so long but then I figured out that her 8pm nap (bedtime is 11) was causing her to not be as tired so she wouldn't sleep all the way through the night...Then again it could also be the change in sleeping arrangements that have him out of synch...see if it's still happening when he goes back to his own crib. Good Luck with all of it!
