We have the P&T's too and we love it. It doesn't get used much now as they are pretty good walkers, but we had no problems using it with the two boys (19 months apart). But I did find my sling was my most useful possession in the early days with both boys. They sleep so easily in the sling and it's much easier to get around without a pram. When DS2 was born, we still needed the pram for DS1, but I had DS2 in the sling more often than the pram. We used the toddler seat anyway, so that we could have two in the pram, and if only one was in there there was plenty of room for bags as well.
