I am an impulse buyer too... also been working on that beause honestly I buy things that are just wants or even worse things we really do not want but it is a good price and I can find a use for it. My daughter has A LOT of clothes, more then I do, but it is hard to walk away from a cute shirt/pants if it is a resnoable price. I also buy ahead of what my daughter needs when it goes not sale (we do get some handyme downs but not a lot). I am by far not the best to judge on the "typical" scale because I have issues to work on when it comes to money BUT here is what I visit in a typical month:
Gorcery Store go 3-4 times a month, spend around $400 for food for 3 people PLUS another $50 for acholic drinks and another $50 if we are having people over for dinner/lunch (which happens about once a month, sometimes twice)
Walmart & Target go 1-2 times a month (not 1-2 times each but either or 1-2 times a month), spend around $100 each time I go, items gotten usually are the paper products and necessities like pull-ups, hydgen products, cleaning supplies... BUT this is where I can get off track and buy those clothes that are not really needed but are cute or that basket is so much nicer then the one I already have which is kind of starting to fall apart (so I know I can save and am trying to cut this habit). I use to go ever week but have cut that habit because it really was not needed.
Mall... 4-5 times a year... usually go at christmas time 2-3 times to look for gifts and one or two times I want to buy a new dress or outfit for a specail occassion. I USE to go to the mall every month and sometimes twice a month BUT the money was not spent wisely so I cut myself off from the mall (very hard to do, because I LOVE going but it had to be done, saved use about $500 dollars).
NOW when it comes to other things like toy stores, baby stores and so on I use to go at least once a week when my daughter was first born... not cool but that has changed so what I started out on spending has dropped A LOT. I am not a coupon clipper, have tried but just can not do it. We also have NO extra storage for bulk food items so I can not buy a lot of an item when it goes on sale (wish I could but maybe when we get a new house).
In the end you have to live with-in your means. Pay all your bills, buy what is REALLY needed, put some money into savings account and judge by what you have left. My hubby buys things only when really needed, he is a saver so I am glad I have him helping me out since I can be a spender. We always try to have a certian amount in the checking account (bottom line, example no less then $1000 in the checking account), what we feel comfortable with, which will be different for everyone.
Clothing Daughter: 15 pants, 12 skirts, 10 dresses, 20 long sleeve shirts, 20 short sleeve shirts, 10 tank tops, A LOT of underware since we are still potty training, 14-20 pairs of socks, 6 pairs of shoes. 2 winter jackets, 2 spring jackets, 2 fall jackets & 4-5 zipper sweaters. 5 PJs for cold weather, 3 Pjs for warm weather and 3 PJs for in between I try to keep everything contained to a draw, shirts get a drawer, pants/shorts/skirts get a drawer and so on (have five drawers for her clothes plus a closet for coats & dresses)... that helps me to not OVER buy.
Clothing ME: 3 pairs of jeans, 3 kahki pants, 5 dressy pants, 4 comfy pants (yoga/sweats), 2 pairs of shorts, 5 skirts, 5 dresses, 10 dressy shirts, 15 tank tops, 10 cardigans/blazers, 10 comfy shirts, 5 PJs. 8 pair of shoes, 2 winter jackets, 4 spring jackets, 4 fall jackets, 3 zip up fleeces.
PS... sorry for any mispelled words my spell checker is down and I can be a horrible speller when it is not back me up :)
