Astrid, calling them is a great idea...I hadn't thought of that

Yep, last week he was measured at 66cm..he's even too loong for his 0-6month grobags now, I am going to have to get him the next size up..

Jillian, thanks for the info, I will have a play with the seat on the weekend and see. I wouldn't mind so much if I knew his head wasn't going to bounce around a lot.
