I would say no, no and no!
In 2019 my youngest son had just gone through a divorce. He then met a new woman within weeks and they went off on a lovely holiday.
About 6 weeks later he called to ask if I could loan him some money as he was having very temporary cash flow problems with his business. Also found out two days later that new partner had just discovered she was pregnant.
I thought it over for days then told him I couldn't do it as he has two other brothers and if they came to me with the same request I couldn't match it for them.
Now, none of us could have foreseen the pandemic, but if i had dipped into my savings to help him and he had delayed repaying, I wouldn't have survived this last year financially.
It's only been because I had a 'rainy day' fund that I've been able to get by.
