When to ditch the carry cot on travel system

[nightlarking]

How old was your DC when you moved from the carry cot to the pushchair on your travel system?

3 months, BUT please dont sit them up before 6 months, their bones arent strong enough and tmi think the pressure on the base of the spine is the issue. We reclined our seat and purchased a generic infant insert for additional support :)

6 months, maybe closer to 7? I was in denial about her not being a newborn anymore!
