I have similar memories but now I have my own children I've interpreted them differently.
she wasn't often fun, she shouted sometimes, we mostly did as we were told by her. I don't remember the cuddles when I grazed my knees, I don't remember much beyond being told if we didn't behave we would be sent outside to play.
I remember being taught to play poker and whist by my dad. I remember playing monopoly with him, I remember special days out to places and being taken out on my own by him as a special treat without my younger siblings.
The truth is my mum was like air, critical to survival but just there in the background constantly keeping us alive with no credit given.
She did every wake up, every breakfast, every lunch, every school drop off and pickup, she washed everything, she gave us every bath, she cooked every meal, she read to us and listened to us read, she picked us up when we fell and gave us a sugar lump to make us feel better, she did the nights, she did the days, she did the holidays.
and yes at times she resented it all, and yes sometimes she was grumpy.
but she was just there, unlike dad who wasn't. He is/was a perfectly lovely dad but he wasn't there and so I remember the times he was because they stand out.
and he was cheerful because he wasn't doing the daily drudgery and we all loved him much more than mum because he was special chocolate, not air and he never told us to tidy our rooms or to get in the bath.
My mum now admits she probably had some post natal depression, as have I. I haven't found small children enjoyable. Luckily unlike my mum I can talk about it and not just be written off as a shit mum.
