Yes they are supposed to be able to support themselves a bit, but you can stuff things round their head to help. My son loves it, we go to the canal and look at ducks, boats etc. Its a great workout as I have to talk to him all the way thru!
Tubes stuffed this morning, had a 10.15 hosp appt at Barts should be able to get there in under an hr but had to leave way early and was still late. Did manage a 4.5 mile run in the rain first though!
Get a running buggy! Esp if you both run. Lots of us have used them. my last baby is 2.5 now so will prob not use it much more. It was second hand on e bay when I got it, and I've loved it. Will prob hang onto it for another yr or so though.
