Well if you want a cheap holiday you wouldn't be looking at all inclusive foreign holidays :) ... you'd be looking more at camping, haven or possibly a mini break with premier inns as a base.
Or like us you just don't have a holiday.
It all depends what's important to you.
At one point our income was very high. I didn't think anything of buying all my make up at chanel and I once arranged for a particular dress to be couriered to me from London to norfolk for an event.
Gradually we have whittled it down because we both like me being at home. You find you spend less being at home. You don't need fancy work clothes and make up and 20 pairs of shoes. You might want them - and that's up to the individual- but you don't need them. I have 2 pairs of shoes now. Converse and sandals. That's it. I used to have a wardrobe just full of shoes.
If you're an anti social old trout like me you don't spend money on going out because you actually don't mind having no friends because after spending your life being surrounded by people having peace is very therapeutic. I don't smoke. We don't drink any alcohol. We have Netflix for entertainment and do a lot of walking and getting out and about to parks etc. We are lucky to live in a nice rural ish area. Not so easy if you live somewhere more urban.
We also find that whereas when we both worked we would spend loads on take aways and convenience foods we now spend less because I've got the time and interest to cook. I make cakes. I cook from scratch.
I don't have hair cuts. I cut my own hair and just tie it out of the way most of the time (I used to spend £150 on a cut and colour).
We budget down to the last pound. I write everything down that we spend in a notebook I keep on the side in the kitchen. If we go over one week I make it up the next. I ebay old to buy new where I can.
I think it's one of those things where not everyone can afford to have a sahm or dad but certainly if it's important to you it's worth cutting things right back and seeing what you might be able to do.
I might go back to work when ds is older. I might not. I love being at home and don't regret leaving my job even for one second. I guess everyone and every situation is different.
