Oh hun

I understand, I grew up poor/struggling too so now as an adult starting a family I only just understand the stress my parents went through. But you know, we were happy. We had each other and we were looked after and did simple things. I shared a bedroom with my younger brother (15 months apart) and younger sister (6 years apart). Sure, we fought but we were all best friends. Kids are resilient, I know it will be hard and this probably isn't all that helpful, no one wants to 'just survive' but your kids will grow up learning to share and appreciating things (not that they wouldn't otherwise, but in my experience well off people really just don't have a clue how hard it is at times).

For what its worth, my dad grew up in a family of 12 kids in a 3 bedroom home, and not the modern kind with theatres, play rooms & ensuites. They're all fine

You are here now and there is nothing helpful in feeling guilty about perhaps not thinking it through financially first.

All the best x
