ds is 13 weeks and has not slept well for weeks usually wakes every two hours and rarely sleeps during the day unless we are out in the pram or sling. This week he has started crying when I put him down if he has fallen asleep he wakes in minutes. I tried leaving him on his side and that didn't work. He is bf and feeds alot so I don't think he is hungry and falls asleep during feeding but not every time.
Any suggestions of what to try to encourage sleep ?
