wow, i really sympathize with you.....my daughter did not sleep through the night until she was four, i have a 16 yr old son and 12 yr old daughter now, all children are different, when you say you've let him cry it out, i understand what you say when you give in after your three year old wakes up, my daughter would SHRILL scream for hours and my son (5 yrs at the time) would cry too and say, please mommy , im sleepy, make her stop crying, it was awful, they had to share a room at the time, we lived in a really tiny house. If I had to go back and do it again, i would put that child in bed with me and save everyone years of grief and tears, i dont know if she was just an insecure baby/toddler or if it was control she wanted but all the trauma of trying to get her to sleep through the night wasnt worth it
My advice to you would be to do what is best for your family. Clearly, he is not hungry or uncomfortable. He may just not be ready to sleep through the night. Meaning-all his physical needs are being met, but he needs the assurance of you comforting him with a bottle twice a night, all children are different, your pediatrician doesnt know your baby like you do, he is only 10 months old. Giving in after 45 minutes given your frustration and your 3 yr old issue is completely understandable, but a baby with a strong will and a need can sometimes go alot longer than 45 minutes in the crying department. You may have to commit to a couple or three all nighters to really get that to work, but if you cant do it, dont beat yourself up, i know it seems like this stage is going to last forever but trust me, he wont be a baby forever, and the next stage is right behind this one...relax, you will make the right choice for your family and your baby
I wonder if your husband is supportive of you trying to get him to sleep through the night, by supportive i mean, is he rolling his eyes saying "let him cry, he'll be fine" or "do something!" my husband didnt know what to do and always wanted to "give in", that made it so much harder for me and added to my stress
good luck to you, i know what you are going through is hard....more than hard
