I know booster seats are for 4-8 yrs but also 14-26kg.
Ds is 2 yrs and 3 months but tall and has outgrown his car seat that is supposed to last till he's 4.
He weighs 14.7kg and I'm pretty sure the only option is to put him in a booster seat with seatbelt and harness.
Would you do it?
Do you think it's safe?
