Earlier quoted context omitted.
If you could not pay your mortgage could you not sell and rent privately? Please don't take this as a critism of your decision - I made mine and I am happy with my choice, but I don't expect that what is best for me is best for everyone.
Private renting in my area (as with a lot of places in the UK) would be more costly than my current mortgage. I didn't think you were criticising parents who use childcare, least of all me, but I do feel it's necessary for people to understand that the "I'm too good for daycare" argument comes from a position of massive privilege.
I don't think the choice of not using daycare is one that can only be made from a position of massive privilege, but it does involve material sacrifices if you are middle class.
