Just get an ordinary backpack. Changing bags are a big scam really. Any bog-standard backpack for about £20 from somewhere like Sports Direct will have plenty of different pockets and compartments and last for years.
I have a North Face for my office and I use it out and about with the baby now that I'm on leave. I agree, changing bags are waste of money, just get a bag you'll keep on using.
I agree with previous posters and so have been using my old cath kidston backpack - however have just purchased a changing backpack from amazon as was finding it annoying not having multiple compartments. Will see if it’s any better once it arrives.
Pacapod bags are great for this. Love mine, started off with a "normal" bag but it didn't work for me. I have the Hastings bag, it's on sale on their website 🙂
I had a pacapod and loved it, but then decided to get a backpack and it was much better. They sell them on eBay for £20 and have slots for the bottles and wipes etc. It's been going strong for a few years
