My nearly 3 year old is very tall and quite heavy as well (16kgs).
She doesnt seem to fit in my rear facing two way elite, even though I thought it was until 4 years old??! Her knees are literally jamming in her chest.
Can she go in a booster? she is big, but I still want a harness, rather than seatbelt considering she is still just about 3.
Can someone recommend something? what would you buy?
