I think I must be Mrs Mean. I don't work and my husband only earns £19.5K, which works out about £1200 a month of which £450 goes on mortgage and most of the rest of bills. We basically don't have anything left over for luxuries. However we always have plenty food and drink and we own a car.
To save money I use washable nappies, don't buy wipes (use flannels instead), buy all my son's clothes at nearly new sales, buy my own clothes in thrift shops or sales, don't buy any packaged food, don't buy baby food like special yoghurts, instead buy a large pot of yoghurt, buy 'value' products. Also my husband goes shopping every fortnight at around 8pm when they reduce all the nearly out of date stuff. Most of this ends up in the freezer. We save a lot of money on food this way. Don't buy tissues, use toilet rolls. don't buy magazines, make-up, perfume etc (usually ask for this kind of stuff for birthday/Christmas). Don't spend money on unnecessary meals out (save up for a treat), cups of expensive coffee or drinks out. If you do go out then take your own food for a very young child or take some off your plate.
I could go on... but it is actually about saving the pennies and they do turn into pounds. I am always surprised at my richer friends how often they go out for meals, drinks, trips to Burger King and the like and yet they never seem any happier for it.
We also have one proper holiday a year which is a last minute bargain break.
It is hard because for instance not buying convenience food means more time in the kitchen cooking and I often have to walk further to get to cheaper shops. However I have more time anyway due to not working so it all balances out. I feel that I am enjoying the time spent with my child and he enjoys so many simple things that cost nothing or next to nothing anyway such as walks in the park, playgroup and swimming. Also there is only one of us stressed and tired from being out at work all day.
