I have ds 3 and dd 21 months and must admit to still using the double buggy an awful lot of the time. It's just so much easier to get from a to b with them both strapped in the buggy. What kind of distance should ds be walking now? How should I go about it? Most importantly how do I stop him from running off in shops without shouting and making a scene??? Any advice apreciated. I think it's about time to get rid of the double buggy.
