Very little help or support from my parents in any sense of the word.
Divorced parents, Mum was on benefits and Dad paid no financial support for me and DB. DM often struggled to pay bills and we frequently had no food or heating, so my earnings from part time work while doing A levels were used to fill these gaps and buy clothes. Anything left over I used to have a social life. Went to uni at 18 and my Dad gave me £50 to cover the cost of food while I waited for my grant to arrive.
Anything I earned during uni holidays was needed by my Mum, so I stopped going home in the summer and took hospitality jobs that involved living in. My Dad once drove me to one of these jobs as it was a difficult place to get to on public transport.
After graduation while working in a low paid job, my Dad once paid a month's rent for me when I was hit by a few higher than expected bills and was struggling to cover the following month's rent.
My parents did occasional babysitting when the DC were very small (can count on one hand the number of times).
We haven't always had much money, but I never wanted my DC to experience the anxiety of having parents who can't be relied on. It sounds like a low bar, but I'm grateful they've never known serious hunger, been cold at home or had to sit in the dark thanks to no power. They live at home rent free, we paid for driving lessons and covered the costs of any hobbies. Our house was the 'go to' place for their friends to come round and they've had a pleasant and relatively carefree upbringing (as I wish all children could enjoy).
