When should I stop putting ds1 in the double buggy when we go out? He's 3.4 and has just started five mornings a week at nursery. I take ds2 in the single buggy to pick him up, but he gets very tired on the way home. I am thinking of looking for a buggy board. But at what age is it silly to still be using the double buggy on days out etc? I am quite confused about this....he comes out of nursery with his book bag, looking like a five-year-old, and I'd feel silly putting him in a buggy - but he can't manage a whole day out walking, he gets tired. And I like the idea of a buggy board for short trips but not all the time.
