My almost 5 month old is having trouble sleeping during the night. He will have a bath at 7.. then wind down after then 7oz of formula at 8 then into his sleeping bag and usually asleep within 10-20 mins. He has started to wake screaming at 11:30 so I feed him and he goes back to sleep by 12:30 he will then wake again at 3 and I can settle him again in about 30 minutes. He will then wake again at 5am and want to get out of the cot.
I dont know how to encourage more sleep during the night. Can anyone help?
