...when the baby doesn't sleep through?
I don't know if it's a daft idea, or worth a try. We have a small 2 bed house, DS2 is 7mths and still in our room. He wakes a few times a night, and i usually bring him into our bed around 1am.
I think our creaky bed / floorboards / us coming to bed might disturb him more, and wonder if he'll sleep better in a dark, quiet room with his brother. DS1 is almost 2yrs, sleeps through, and he can sleep through DS2 crying in the day.
When DS2 wakes at night, he doesn't cry v loudly, and as soon as he's picked up / breastfed, he's asleep again.
Is it a stupid idea to try them in the same room, or worth a go?!
