Moving baby to a car seat - what age?

Dylan doesn't look skinny but he must have my build. His dad although over weight is also small boned.

Julz, Dylan doesn't look so small on his picture.
Stefan is also far over 10 kg's already! And is getting to big for his peg perego seat even though it will still be a while before he reaches 13 kg.
I wanted to keep him in it till a year at least, but will have to change before that, because the straps are coming out of the top holes already and his shoulders are growing past it now.

I think my sisters little girl is still under 13 kg at 2,5 years. She is tiny and sooooo cute!

No my little man is very little.

err ... maybe my little girl is not so little ...

Dylan weighs 9.6kg at 16 months!!! Still fits in his peg seat but is getting too tall.

I moved my baby to car seat when she was 9 months old mainly because she was big and somehow moved around so much I thought she must have been uncomfortable. I used the smaller one in the hous for when we were watching tv. It helped a lot, I put it in the sitting position when ever I wanted her to sit still I just put in it and gave her teething biscuits to nibble on

Thanks, my baby is around 11 kilograms at 10.5 months and it appears to be nearly spilling out.

I think she probably has another month in her snug and safe, but it is definitely time to go car seat shopping in the next two weeks and find something that works.

She is so heavy and so big, moving her in and around the snug and safe is so cumbersome, so I am looking forward to strapping her into a car seat.
