Is the only option The Donkey?
I've had a bj mini gt, which was fab but I hated that it didn't parent face and dd1 was a big baby who grew out of the carrycot in 10weeks! I wasn't confident or happy to put her in the main seat. I just felt I needed parent facing. So we switched to a Cham 3. I love my Cham 3. DD had ample room in carrycot until she was 5 months and has been really comfy in the seat since (she's 13 months) and it's her napping place of choice. I still put it in parent facing mode so we can chat / talk etc
Now due dc2, dd1 will be 21 months when they're born and I've figured that a double buggy is unavoidable.
I've looked at the bj and mountain buggy duet - these don't appear to parent face. I hate the idea of one under the other too, so that's the Phil & Ted's out.
Maybe I'm being too fussy. I don't know. Could i do dd in pram and baby in sling? I had a bad back after birth last time but maybe just have to get on with it?
Other considerations are that we have a small edwardian terrace with a narrow front door and live in a village with narrow pavements. I've seen one Donkey, once in our local Coop and it looked like a nightmare tbh. However, this really feels like my only option at the moment.
