My son is 2.9, DD is 7 months and we have a double buggy, which he normally quite happily goes in, although I've heard of other toddlers this age who refuse to do so. I've been experimenting with not using it so much over the last couple of days.
I am wondering whether people who say they don't use a buggy any more drive everywhere. I don't usually have the car in the week so am reliant on walking or public transport. Today, we went to a stately home type place with a working farm and playground. DS walked and I had DD in a sling on my back, with a shopping trolley for all the paraphernalia without which we cannot leave the house. We had to walk to the bus stop at the end of our road (five minutes away max). It took half an hour, as we had to look at all the berries, flowers, trees, cats, etc.
Then when had to walk approx. 10 minutes back from the farm to the bus stop. I allowed half an hour. We missed the bus.
I don't like to be saying "Hurry up" all the time and it's lovely to potter along looking at things, but if you're reliant on public transport or just have to get somewhere at a certain time it can be quite difficult. I'm just wondering at what age your children stopped using the buggy, and how you get anywhere once they do!
