I hate it! My mum doesn't give advice, but for every decision that we make, she always says, "we didn't have that when my kids were babies" she's 50, her youngest is 16, there wasn't even smartphones. I track everything on Huckleberry, and she hates it. She always says I should just do everything in demand, which I do, but I track so that I can answer doctors' questions easily and know to keep naps on track.
This can get very annoying. Especially when it's compared to old ways. My mom means well but she compares things to when me and my brother were babies, I'm 32 and he's 29 this year. Like transition to the cot when I'm ready. She said with me to transition she placed my moses basket in the cot because I knew my moses basket so she did this so I'd get used to the bars before she actually puts me in the crib. 1 i don't have a moses basket just 2 cribs (a next to me 1 and a rocking 1) and 2 this isn't safe. She says 'well it was fine when you were a baby and you're fine' I get that answer with a few things. So I say well a lot of things were fine back then that aren't now, safety laws have changed a lot in 32 years. There used to be car seats that looked like a child swing, that was considered safe it certainly isn't now.
I can’t stand unsolicited advice, especially when it is outdated. I usually rebutt it with stating that the latest research states such and such and they quickly shut up. Or I say “oh that’s interesting, guidelines NOW state…”.
