I'm so glad you were able to get pants for your boy. It's such a basic necessity and something people like Hinch don't even consider when they're out there showing off about their two homes, under floor heating and pointless pot filler tap. Just imagine how many pairs of pants that could have bought!
If you're sharing a bed, you should really google Every Head a Bed and see if they can help. You might also want to download Trash nothing. It's great for freebies and not as well known as FB market place so not as competitive when people list things. You can make requests there as well so people will get notified if anyone in the area is looking for toys and furniture.
Oh edit also to say, I saw on the news this morning that in all Asda cafe's kids can eat for £1 this summer with no minimum spend required and no requirement for adults to also buy a meal

Second edit to also add that kids eat free in Morrison's and Tesco cafe's as well.
