At that age unless you are doing loads of walking I would just get a buggy board. I use my Maclaren at the shops with either one in - today Mister nearly 3 wanted to walk and Miss 4 was feeling lazy so it worked well. If both want to get in Izzy usually has to walk for a bit. If we are going somewhere like the zoo - we will usually take the P&T and I use it for walking to and from kinder - its 45kgs with both kids in and hard work but I still love it and it is a great work out.
