Can I hop in in the vain hope that I'll be able to keep up?!
DH and I are living with my parents whilst saving for a house. Having had a mortgage application turned down due to 'low credit score' 
and missing out on a great house (one of the very few that's come up in this area!) we've realised that we've either got to aim for a more expensive house to avoid the cash buyers who do up houses to rent/sell on or a 10% deposit, both of which would require a bit more cash. The "low credit score" is because we've never been in debt, pay off our credit cards each month and have never had anything big on finance But if we get a 10-20% deposit we'll be much much more likely to get the mortgage
So we need to start being a bit more frugal to get that 10%, which is another £8-10k. We have £7k specifically for the deposit but a bit extra floating around if we find somewhere that needs marginally bigger deposit. I'm religiously going through our YNAB every few days to see where we can cut spending even further, though I think we're at the point where we need to look at our food spending (currently £250pm not including takeaways 
) which is difficult as I'm gluten free, I'm also vegetarian, which makes it extra fun! And not having a huge amount of space means that we can only do a limited amount of batch cooking and bulk buying before our two small cupboards and fridge/freezer are full!
We have a nearly 3mo DD as well (I'm on mat leave until the beginning of June, then I need to find work on weekends) who causes us to go through a ridiculous amount of wipes despite using cheeky wipes for changes done upstairs, so we've just bought a second cheeky wipes set to keep downstairs in a bid to save £30-odd a month.
I did two small food shops in Lidl and Aldi yesterday and spent around a tenner in each, I was impressed by how much I got! I usually go in there for bits and pieces but I may try using it for my fruit and veg on a day to day basis instead. And I didn't even look at their bargain bins because otherwise I'd have spent a lot more
At the end of the month we're going to buy zoo passes for two years, it's about £100 each for DH and I but it's 20 minutes away and we could easily go at least once a month, I'll probably go more often with my BIL and nephew and once DD is toddling around, so in the long run it'll be a lovely thing to have. We're lifetime NT members too but the closest ones to us now are just over an hour away, which I don't fancy doing until DD is a little older/feeding is a little more settled! But that will sort us out for family days out for a little while I think!
