Hi, I have had an icandy peach for nearly two years and I love it and it's brilliant. My daughter is 22 months and the last few times I have taken it out it has tipped over completely forward once when going down a kerb so that was my fault but today it nearly tipped over twice when going over small little ledges in shop door ways. Does anyone else find this? She can't be too heavy for it as I think it's a 25kg weight limit for the pushchair part.. Do I need a different sort of pushchair now she is nearly 2? Thank you!
