DD1 is 3 next month, DD2 is 1 in November. They sleep in separate rooms at the moment but we have always planned to have them share, even though we have 3 bedrooms.
However I read something in an article saying it's potentially dangerous to have a toddler and baby sharing because the toddler might put blankets on the baby's face or something like that. Is this a serious concern? I'd never considered it before. Baby will be in a cot with high sides and DD1 has already moved into a single bed with a safety rail so can get in and out on her own.
