My 11 month old has recent decided that when it's my nights he wants to be up about 3.45/4 o'clock in the morning but on dads nights he doesn't get up until 5.30/6 in the morning. We don't do anything differently to each other. I've tried the no talking to him and cuddling him, giving him his 1st bottle in the dark and everything but nothing seems to work he still wants to be up. He does about 3 hours before he goes back to sleep and it's hard as I have a 7 year old who I have to get up with as well and get ready for school.
