My son is almost 7 months old and until a few weeks ago was sleeping from 7-8 pm until 5 am before waking to eat and go back to sleep till about 7am. The last few weeks thta schedule has gone!! Now he's going to bed around 7pm, but waking around midnight, and four and six......I try to let him cry (while checking on him every 15 min) but not picking him up or feeding him. BUT once he hits 45-1hr, I can't take it! I end up feeding him and fear this is making my issue worse. Does anyone know why this is happening? OR have any suggestions on how to get my baby sleeping again??? I feel like he's a newborn!!! AHHH..
