I've got three "two people" prams. I knew I would need a double of some sort given DD#1's age, and at almost 18 months I still don't think DD#1 would be very comfortable in a conventional toddler seat. I originally bought the Valco side by side because DD#1 was only 12 months when #2 was born - still very much a baby and I wanted good, comfortable pram seats for both girls and a good pram for long walks for my benefit. Weighing in at just under 20kgs and not exactly the most compact thing when folded I bought a Babylove tandem (one in front of the other) for my "shopping/car" pram. I hated it because the front seat (for your toddler) always seemed to be uncomfortable for Iz - she slid forward and never really seemed totally happy in there. So, Pram No. 3 is a Phil & Teds, which is now my shopping/car pram. Folds up small and is very manoueverable. I'm still in two minds about it - I think it is the very best option for getting around the shops but I agree with some of what Belle said. I also find it very unstable going up/down stairs with two babies in there - seems very, very easy to tip. So, if you are only getting one pram I would go the side by side. As big as they are, IMO they are the best bet for safety and comfort.

If you're interested, I've been "getting around" to selling the Babylove tandem. You're welcome to give it a try and see what you think of it - surely it has to suit some kids?? If it suited your DS, it would be a cheap shopping/car pram for you.
