thing is, young mothers today (like myself) are more into the "fashion". i'm 20 and my daughter is going to be 2, & i recently bought her an ECKO dress, it came with the little bloomer/underwear thingy. i thought it was adorable. SO i bought it. you don't have to but things you don't like, so don't. it's your opinion, and others, i'm sure. but there's a wider variety that is going with the flow and the NEW times.
Way i think of it is, my daughter's a baby, she's going to take off her diaper and run around the house, and be a kid. she's going to be a kid while she can, and dress cute while being a KID.
But this is just my opinion. Adam and Eve were naked, so i think of this as and evolution of clothing. think of it how you want to, Only god can judge you. & i could care less how people judge me or anyone else for that matter.

Kids will be kids.
