Which pump for pram tyres?

Hi i have the out n about nipper buggy and one of the tyres has gone flat. I tried a football pump which didn't fit. The buggy pumps i've seen online cost ??9 which seems a bit costly if a normal bike pump will do the same job.



Just wondered what others with buggys with tyres use to pump them up, before i splash out on the expensive one



Many thanks
