Some pushchairs are suitable from birth, such as the one Tyrone uses on Corrie.
I've just moved DD (5 months) into the pushchair of the iCandy Strawberry. It's supposed to be for 6 months upwards but she's a big baby (98th centile) and has good overall strength and head control. She seems very comfy in it. She hated the carry cot beyond 8 weeks so we have been using the car seat attached to the iCandy chassis for short trips out or our Baby Jogger City Mini for longer ones which is suitable from birth but isn't parent facing and I perfer to have her facing me as much as possible.
We had a pushchair (iCandy Peach) with a carrycot suitable for 0-6 months, but by 4 months DS was way too curious & wanted to see stuff, so we started using the seat thingie. We'd keep it in the almost flat position most of the time but DS was much happier to be able to see.
Think I got DD into maclaren stroller at 3/4 months. It could fully recline if needed, eg if she was sleeping, but actually she hated it fully reclined so we had it in pushchair or slightly reclined if she looked dozy.
our 1st buggy had a really big seat so ds1 looked lost in it, but it was summer so no liner or anything. ds2 was itching to be sat up around 3months old to see what was going on so I got a stroller suitable from birth with a recline and put him in there. what buggy have you got?
We had DS in the pushchair from the time we thought his head control was good enough to sit upright(ish) with a rolled blanket around his head for a bit of extra support, so I think around 3-4 months. At 6.5 months I still have him facing me, and don't intend turning him around any time soon, because I love seeing his face and talking to him whenever we're out, and so does his dad. Yep, we look like loons
I'm just wondering what age you sat your DCs up in a pram. My DD is three months and is now far too nosy to lie in the carrycot part. The other option is the car seat bit- thus bad for her back. The carry cot bit sits up, into a seat with a buggy bar. I have a cosy toes and sheepskin liner and it can face me or front face. I'd just like some advice please as I notice in Coronation Street Tyrones baby has been in a stroller since birth which I thought was frowned up
