I have a 4 month old little boy who goes to bed at 8pm every night, he’s flat out and sleeps really well until around 2.30Am when he wakes up for a feed. After this he really struggles to sleep, he will fall asleep for about half an hour then wakes up trying to trump and does this until around 8am when he has his next bottle, he flails his arms and legs around and cries out in frustration that he can’t trump but it’s only at this time of the morning but it’s every night and I have no idea why, can anyone recommend what I can do to help him get back to sleep and stay asleep and not having him spending hours obsessing over trumping?
