Backpack for mum of Toddler

[Skate82]

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.

My toddler has his own backpack too....but 95 percent of the time I end up carrying that also.....

I'm a long way past toddler age so don't have any experience with this brand but but what about this one tibaandmarl.com/products/elwood-changing-backpack-silver

I googled baby changing rucksacks and there seemed to be loads of good options.

I’ve had a Fjallraven Kanken since eldest was born.

Never used a pram much - preferred a carrier - and it’s always been great. Changing mat in laptop pouch plus the plasticky bit it comes with for you to sit down on at the park when it’s soggy, an old makeup bag with a few nappies in, some wipes. Clipped a portable potty to the strap during potty training (all the glam).

Now they are 3.5 and 1.5 I have two small fabric drawstring bags at the bottom with a change of clothes. Two side bits for a brolly and a water bottle. I like the way you can unzip it all the way round and access everything easily.

It goes in the wash and I often wear it to work now.
