I used this as a mother's bag 6 years ago (*^^*) It's incredibly spacious!! Flat measurements↓↓↓ Height: 33cm x Width: 38cm Depth: 13cm The handle has some padding, making it soft and easy to hold! There are 3 compartments inside♫ (Photo 3) Each opening is large, making it easy to put things in and take them out! What I actually carried when I went out (twin infants): 2 thermos bottles for making milk (hot water and cold water) Powdered milk (about 6 stick packs) 2 baby bottles Snacks for 2 10 diapers 2 drool towels 2 bibs As far as I remember, I could fit about this much! It doesn't look that big, but it held a lot, lol. There are no noticeable stains, but please refrain from purchasing if you are overly concerned about minor imperfections. m(_ _)m
