My little one is 2 and I am desperate for a 3 wheeler. I have had loads of pushchairs so far so it needs to be quite cheap so I can justify it to the other half. I live in the town and drive a small car so it needs to fold small etc. I do want to take it over rough(ish) terrain & def on the beach (although not regularly) but am a bit unsure of the pneumatic tyre thing as am concerned about punctures .. all advice welcomed (plus any decent justification that I can use to help convince my hubby that I need another pushchair!!!!)
