About 3 months I used the seat but laid flat
We did it at 3 months as he was very alert and liked looking around x
It’s recommended at 6 months or when your baby out grows the carrycot.
If your pram lays flat then it can be used from birth. I moved my girl around 11 weeks as she hated laying in the carrycot x
We have just moved over at 5 months as he has outgrown the bassinet. He slept in it so well though I wasn't in a rush to make the switch. Now he loves the stroller, still facing me but looking out and seeing more ❤️
We were planning to change him now that he just turned 5 months, but our osteopath said to wait another 2-3 weeks
I did at about 2.5 months but only because she HATED the carrycot (I think laying flat aggravated her reflux) and I was stuck in the house very isolated because she would scream and scream every second she was in it. I used the seat on the lowest incline (just one up from flat) and it changed everything for the better. I just watched her very carefully while she was in it.
