Also if it is an issue of them getting tired in the shopping centre, then I jsut chuck my nearly 3yo in a trolly! The baby is still in a capsule, and I will try and keep her in it, till she is able to sit up properly in the trolly, then I will still use the trolly option.

I have a pram with a toddler seat, and although DS can walk, he often jumps in the seat for a free ride
