My baby girl just turned 4 months! She’s been sleeping in a halo bassinet beside my bed. However, I think by next month she will have grown out of it completely😭 idk what to transition too, and also I want to make sure I’m doing what’s recommended to reduce the risk of SIDS. Do I buy a pack and play and keep that beside me? Or do I start putting her in her crib across the hall? (Her room is not big enough for a mattress, so she would be alone in her room)
