Mum to Jack he may be having a growth spurt, so is wanting to eat more frequently...BJ has just had one (Im pretty sure) he used to go from 7:30pm til 2-2:30am, then all of a sudden he'd wake at 10 and 1, and 4...or 11:30 and 3, and 7 etc...then last night he was back to 2:15 and 7:30am so we'll see what tonight brings!
