So my son will be 5 months on the 24th. All of a sudden he wants to eat every 4 hours instead of every 3. His last feeding of the night last night was around 7 and fell asleep around 7:30. He then woke up for a feeding at 2am and fell asleep soon after. And it's 4am now and he is wide awake! I have no clue what to do. He used to sleep from 5:30pm to 6am with a couple feedings in between. Could this be a weird kind of growth spurt?
