Ds is 7 months old, 10.10 kg at a weigh-in last week. He's big and broad so although he hasn't grown out of the infant carseat height wise, his shoulders are too broad for it, especially in a thick jumper (no chance of him fitting in with a coat). It is already a group 0+ up to 13kg carseat and my dd fitted in it till 19 or 20 months.
Anyway, we have a maxicosi mobi for dd which is a lovely rear facing seat for 9-25kg, I thought I would get another for ds. It says it's suitable from 9kg/9 months - do you think that is either/or and it would be ok for a 10kg 7mo? It does recline so he wouldn't have to sit upright in it.
