I can't for the life of me remember. At what age can they move from the flat carrycot to the buggy style (not upright). Dd has always hated being flat in the pram but doesn't mind it when she is in the car seat attached. She's just turned 5 months - would it be ok to switch the base over now or is there something we're supposed to wait for. Have done this twice already but I really can't remember!
TIA
