What age to go from carrycot to seated pushchair?

Please can experienced mums guide me on this?
Thanks xxx

My DS is 12 weeks and still lying flat or in the car seat/travel system bit. I think I swapped it over for my older DS when he was about 4 months so that he could see a bit more but even then the seat bit or my pram still reclines fully flat.

It really depends on the pushchair and the baby.

I would say when baby can hold his head steadily, so itdepends a lot on the baby. And yes I agree also with Hypatia, it depends also on how comfortable the puschair is, is it padded ? Not too soft ? 5 point harness ? You can try with your baby and will soon find out if it is ok or not, your baby will let you know
