This has been going on for too long now... I feel I have tried everything but maybe not?
He was sleeping fine until he was 3 months old (waking 3 times a night).
Now, he goes down at 8.30, wakes up around 11 and then it is almost every 55 minutes (I look check with my phone and it is freakish-ly regular). He cries and I feed him back to sleep.
This week I started him on solids and I give him 180ml of formula for his last feed. It hasn't changed anything...
What is wrong with him my routine?
