Thanks so much to everyone for all your really kind replies & I've had a look at those you suggested...
I'm gong to sound really picky now because I really need a swivel wheel (I'm used to using a Jane with one) and think it's going to be hard work without.
Also it's for an older littly who's nearly 18 months. We're adopting and the whole idea of the reversible seat is for bonding/attachment to start off with.
I'd be so grateful if anyone has any more ideas - even if it's something older I can look second hand
so a 3 wheeler (good for off road)
swivel wheel
reversible seat
suitable for 18 month+
thanks again everyone
