Okay, ftm and no clue on almost everything at the start. I bought different kinds of diaper bag, like I have 5 bags plus this one so total of 6. I just couldnt get comfortable with the first ones until this came in and started using it. My problem on the other bakpacks diaper bag that I had was they were too heavy. I dont need an additional weight on me because my baby stuff and her is already 25lbs. whee! Could you imagine that carrying around? yes, thats why I decided to take a try on this. this is light weight and have all the partitions I needed.
