OK DS is almost 1 year and about to out grow his group 0 maxi-cost seat.
DD is 3 years and in a rear facing seat that goes up to age 4 ish.
Plan is to move DS into her seat and buy new next seat up for DD. However, that seems to be a group 3 forward facing one that goes from ago 4 - 12 years and more like a booster with a back. She is 15kg now so I think her weight is OK to go into that size seat - but it seems a big jump and a lot less protection than her current seat.
Has anyone else had a similar situation - what did you do?
