Sleeping through the night

You are not alone! :) Mine just turned 4 months and he still wakes up every 3-4 hrs through the night. He will only sleep through the night if we bring him out and he got so tired. But if he sleep through the night, his diaper will be leaking in the morning. I rather he wakes up every 3-4 hrs so that we can change his diaper as he will sleep comfortably :)
