So my baby is 11 months and has been sleeping in his crib since he was a newborn-ish. Teething is killing me, he's waking up loads atm looking for the boob and DH is away, so I'm thinking of putting my mattress on the floor and sleeping with him. Do I start with the crib (he goes to bed at 7.30, too early for me) and then get onto the mattress only when he wakes? How do you do this?
