While i was pregnant i saw an advert in magazine about wheels that attach to your carseat, they click out of the back like a suitcase handle.
I threw the magazine at the time but now my DS is 3months old and between him and the very bulky silvercross carseat my arm looks like i am training to be a bodybuilder!!
I have scoured the internet and found a site in America but i am sure it would have been a UK company to have advertised in a pregnancy magazine here.
If anyone has herd of or seen this please let me know.
