I used to keep 2-3 weeks worth then I gave it all away.
I now am on target for 5 pairs of everyday pants (suitable for play or small errands) and 2-4 pants/overalls/cords non jeans for grandmas', restaurant etc.
I think 5 play and 5 nice work well.
Especially going into school or if your child is in daycare/nursery school.
I do this with hubby too - 5 pairs of non suit work pants - 5 pairs jeans (and two pairs of painting gardening stuff
Me I am down to much less, I have one pair of cleaning pants (bleach, paint etc), 2 pairs yoga pants, and one pair of nice jeans (for going out but not nice places) and two more pair of casual pants. Then I have two jean skirts for those medium casual.
I also got the pijamas down to 4 for each child. They can wear them more than one night, and I am on track to do laundry twice a week it got to the point I was doing 14-18 loads on saturday - talk about mind numbing!
I also went to sorry to say Walmart...but hey nice fluffy towels two bucks! And got two towels for everyone, plus one guest set and one set for each bathroom. I put their names on in magic marker. So you get your towels.
I have 8 pairs of undies now and three bras.
Oh boy I feel so good sure I do laundry twice a week but I am doing diapers anyhow then they get to wear their nice stuff more, instead of just what's clean after a week.
My three year old's entire wardrobe now fits in one drawer instead of the whole dresser
i think if we ever had to evacuate I could easily pack what he needs as its all there!!!
