I need backpack inspiration please, I'm a mum to a toddler who's pram/buggy is almost redundant now. I haven't used a bag (other than the obligatory matching pram changing baby bag) for a very long time as the pram was basically my one stop for everything. I'm looking for a backpack that can easily facilitate all toddler requirements but can also double up as a bag for me to use should the occasion ever arise that I leave the house on my own to do something outside a park or playgroup. I've trawled the Internet but without testing them it's so difficult to chose. Any recommendations very welcome. My budget is upto 100 but less would be better. As a side note if its also water proof that would be a bonus.
