This just happened in the last 2 weeks. My 10 month old son used to sleep through the night from 8pm until 6pm. For some reason he isn't sleeping through the night anymore. He tries to go to sleep at 8pm (sometimes doesn't fall asleep until 9pm) but he wakes up at 10pm for formula even though he is fed at 8pm. He then wakes up around midnight for another bottle. He then wakes up at 6am for his breakfast. At first I just fed him anyway thinking it was a slight hiccup in his sleeping schedule, but now he does this every single night. It feels like the newborn days all over again. If I ignore him (which I tried several times) he will SCREAM until I go in there. Once I was so sleep deprived, I checked on him and decided not to give him his night time feeds. He literally screamed ALL NIGHT LONG until I went in there at 4am with a bottle...then he started laughing when he saw it and drank it. :/
I feel like this is my fault since I kept giving in. It's starting to really effect our sleep. The home nurse told me not to give him any formula at night, maybe a sip of water if he's thirsty but no food. My son will not have this though. He screams so loud that I am scared the neighbours will get angry at us. The home nurse said he is past the age that I should allow night time feeds. She said things like how this can make him overweight in the future if he feels the need to eat all night long...and it will do more harm than good in the long run for all of us. If I ignore him he screams bloody murder though...so then I will feed him just to get a few hours of sleep. He has formula and solid meals all day though so he shouldn't be hungry. Help :(
