my boys were 23 mos and 42 mos when i decided to nightwean. they both woke 2 a night (1am and 4am) to nurse. this is after a 9pm feeding and waking up to a 6:30 marathon.
I don't recommend nightweaning. that is something each family must decide.
but i was had just gotten thru my 1st tri of my 3rd preg, not feeling good, and was not sure if i wanted to nurse 3 at night. plus, the boys slept well when they slept at mamaw's.
I expected it to be a long process. But it took a month. Phasing out each feeding, holding hands and cuddling instead. I still nurse throughout the night when they are sick.
Now, my boys are 3 1/2 and just about to turn 5. My 3 1/2 yo sleeps all night without a problem (most of the time) MY 5 y o. does and always has woken during the night every 3-4 hours. He will come find me no matter where i am in the house when he wakes. I wonder too if he has sleep disorders and then i remember as a child that i always had a hard time sleeping. hard time unwinding the brain until i discovered reading.
i don't worry about it. my oldest does get to nurse at night right now because i'm too confused anymore when i'm sleeping. i don't know who's in my bed and i'm so used to nursing my little girl, i wind up nursing others thinking it's my dd.
i think you should hang in there and not worry about what others are telling you. i think you'd know if your child had a sleeping disorder by now. great job trusting your child's needs!!
