My little one is starting pre-school soon and has selected this school bag :) Babymel Zip & Zoe Mini (for 1-4 yr olds) backpack is just the right size for small ones yet roomy enough to put essentials, with padded back straps for comfort. Another plus point? Machine washable!! They come in many cute designs too.
Usually $32.90 but now on sale for $15 at Motherswork.
