Have posted here as I think will get more response than in Products
DS will be 3 in May. He is 2st 7lb and his car seat (Britax First Class Si) goes up to 40lb so he is nearly at the max
Although he is tall for his age, he is not ready for just a booster, so I think he needs something in between car seat/booster -high backed booster??
Any help or tips for me please?
TIA
