Pigeonpie I really like the look of the healthybackbags although there are so many to choose from! When you say you have the small one do you mean the small backpack type one or the really small almost purse size one?
I currently have the tote bag which I use daily and it does get heavy. If I'm going out with the children I have a rucksack but it's not a proper rucksack it's a nice looking material one from Accessorise so probably no better for me than a normal bag.
For day to day & work some of the things I cart around are large purse, notebook, phone, iPad mini (only take this to work nowhere else), make up bag (never remember to touch make up so pretty pointless really), tissues/small pack of wipes, any paperwork I need to deal with on lunch break (usually A4 size folded in half), random bits relating to dc's (cuddly, toy, small book etc), bottle of water.
In the dc's rucksack I will put drinks bottles (find these bloody heavy), snacks, hoodies, waterproofs, snacks, wipes, spare pants for dd, colouring book (why?.?.). To be honest we don't go out that often in the week to places that require all this and if we go at weekend DH will carry it.
But when I do have to carry it I find it heavy and bulky and it's clearly not helping matters.
Does anyone else have a bag from the healthybackbagcompany? I need to do the right thing to help myself and they look great for going out with the kids but not sure about turning up to work with it..
