Ds is two and a half. He is in own room in a single bed after first two and a bit years Co sleeping just with me. He has two siblings and usually goes to bed first though if dh home I often put middle child to bed while dh does the toddler, or the other way round.
I do bedtime about 70% of time.
I have noticed that when dh puts toddler to bed he sleeps though until about 5am. When I do it he wakes up two or three times in the night demanding milk. We put him to bed with same amount of milk, story from the same stack of books etc. Any ideas? I don’t think I am imaging this pattern.
