Car seat Lexis 4 now and she's 2st 8lb not sure what that is in kg anyway does she need to be in a…

One of my cousins is 4 and he's still in a harness x

Lol my little boy just turned 1 and is 1ib shy of 2 stone ?

I think she's about 16.3kg.

4 is the very minimum recommended age to be forward facing and then using a seatbelt, as long as she's able to sit still and understand not to take belt off or slide it under arms then yes she can but if her seat goes up to 18kg which they all do, then I would keep her harnessed for a bit longer if she's happy to x

She can still use a harness until she's 18kg which she isn't yet, she's not even 17kg so she's got plenty of time before she hits 18kg xx

My almost 5 year old is 2 and a half stone and still in a harness x

18kg is about 41lb so about 3st.

Bert was still in his harness at just over 18kg and he's now just seatbelt x

Sophia's nearly 4 not sure what her exact weight is actually but she's still in a harness
