My mum is 68 years old and quite well. She lives a few minutes down the road. She is retired and on her own since my dad died. During covid she stepped back and refused to be part of our bubble at times. We have a 6yo daughter and a 3 yo son. My son has a speech delay and has behaviour issues. My husband and I found lockdown very tough and argued frequently. We considered splitting up due to the strain of his behaviour and the need for constant supervision. His parents live in Cornwall which is 6 hours away from us. They are older but amazing and so hands on. I feel closer to them than my mum really. We chose to live near my mum to support her but we get little help. She makes us feel guilty and is reluctant. She blames lack of confidence but she has made it clear that she wouldn't like to do a lot of childcare like some of her friends. She has said she would have my son for 1 day a fortnight only while I work. I feel hard done by as most of my friends get more help than us. AIBU to expect my mum to want to help with the kids?
