Hoping to hear good news, did your baby manage to sleep a whole night all by him/her self? if yes then in what age?
My son is 6 and a half months old, he wakes up every hour to three at night, this didn't change from birth. We done sleep training when he was 4 months old, it didn't work, after months and a half I decided that it's enough!! Now I'm putting him to sleep late and when he wakes up I give him a bottle, if he still needs help to fall asleep I move the bed from side to side, if that won't help I will get him sleepy in my hands and put him back to bed.

We stopped the night feeding for two whole months, it didn't change anything and I noticed that he wakes up more frequently if he doesn't eat at night, plus it takes me longer to put him to sleep.
