Tips on how to keep your diaper bag

more organized when you have 2 kids or more ? I have a 7 month old and will have another baby in 4 months. I wouldn't say my diaper bag is anywhere near messy but things do pile up and it gets to the point where i'm starting to worry if when my son gets here I won't have much space in there for both of their things. My daughter will be around or exactly 1 year old when he's born. What I have INSIDE my diaper bag is a can of formula, boogie wipes, a first aid kit, a onesie, pants, and sometimes a sleeper , 3 to 4 toys, baby wipes, diapers, and 2 type of gerber snacks. My diaper bag is full after that
