Can I use it to carry my 4 year old daughter who weighs 17 kilos please?
Hello, yes, you can - even though, officially, the buggy is up to 15 kg. It is, however, rather spacious, and if only for occasional use, it should be able to handle even a 17kg child. Other choices I would recommend (with a higher weight capacity) would be the Cybex Eezy S+, the GB Qbit+ All-City, the Easywalker Buggy XS, or the CBX Etu Plus.
