We live in the north west where cinema tickets and swimming fees are half the price of what they are in the south east where we used to live. So it depends where you live.
We also feel like we both work hard and don't get to see the rewards anymore. We also have a house that needs work doing but we have no idea how we will afford it. It's utterly crap and soul destroying at times.
However, Things we found helped are:
Swapped our monthly take away to pay for Merlin passes (£30 a month) and use it every month
Cancelled Netflix to pay for national trust membership (£12 a month) and use it every month
We save Tesco clubcard points to pay for pizza express vouchers for birthday meals
We asked grandparents to chip in towards swim lessons
We swapped bank account to a bank who offered £175 cash back and 6 x cinema tickets
We only take the kids to the cinema Sat morning when it's dead cheap, bring flask of juice and £1 bag of popcorn from shops
Clothes are all bought 2nd hand on Vinted
We ask for fancy dress costume for Xmas presents (helps for world book day too)
Other than that, lots of trips to the park or playing in the garden and then making it fun in the evening with pizza/movie nights or games nights etc.
It's very hard when I see friends booking holidays abroad, going out for expensive trips and meals all the time, they all have bigger houses than us and I have no idea how they do it.
We can't afford to eat out at restaurants or have spa days or go abroad, but we're trying to make the best of what we have and hope that things will get easier in the future.
