DS just turned 13 months old and is not sleeping through the night. He did at 10 months for a bit but then started waking up once or twice in the middle of the night again. Usually I would feed him a bottle of formula and he would go right back down. I know I am "suppose" to wean him off night feedings but just curious to know if anyone continued to give their LO formula in the middle of the night after one years old? He drinks cows milk during the day.
