I'm needing some advice on convertible booster seats.
My parents are wanting to get one for their car for the child children, 2 x 3yr old and an 11mth old for use when they have one of the children. Ideally, it would be best to get the most use out of the seat for the dollars spent I am thinking a convertible booster.
My son is in the 95-97% percentile for height, but only 25% percentile for weight, and I want to keep him in a harness for as long as I can. My nephew is 50% & 50%.
What would you recommend that has tall shoulder straps and has good CREP ratings?
Thanks in advance,
