I am 48 and find I am much much less patient with my kids and I wondered if it was because perimenopause and into menopause strips you of your nurturing oestrogen & ‘mummy’ hormones. Aibu?
I have a primary aged young child still so was older having my kids and maybe this is one of the negatives of having kids older!! It certainly feels like it!! Anyone else feel like this?
Nope. Not happened to me, but then mine left home by the time I hit my mid 40s. Uni, flatshare with mates, and then lived with her boyfriend... I couldn't imagine having primary school aged children in my late 40s. 
I am in my early to mid 50s now, and DD is in her mid 20s, and has been away from home for 8 years. I still feel love, and concern, and wanting to nurture her, and care for her. (Even though she rarely needs my help.) I have never stopped feeling that way, despite the fact she left home 8 years ago. She would always be welcome back too, and I would pretty much do anything for her (and so would DH.)
She knows all this, and I think this is one of the reasons that she is happy, secure, and independent, and why we have such a strong, solid, wonderful relationship with her. We have let her be independent, and have never put any pressure on her for anything, but let her know we are always there for her.
I know that may not be want you want to hear, and it may even sound smug to you, but I'm not going to lie to make someone else feel better. It's like when someone I knew had a teen daughter who spoke to her like she was a piece of shit, and screamed and stomped around, and smoked, and stayed out til 1am, at only 14 years old.
Mine never did that, and this woman I knew seemed a bit annoyed and irked, and a bit puzzled about that. With a 'surely she isn't THAT perfect, she must do SOMEthing wrong sometimes' attitude, and a kind of
look.
Well, no, she isn't perfect, no-one is, and we do have disagreements, occasionally. But I'm not going to say she's a demon teen from hell to make you feel better about yours. 
Have to say also, I have known a few women like this, whose young teen children are very badly behaved, and out of control and they can't stand it/refuse to believe it that someone else's teens are actually NOT badly behaved, and insolent, like theirs!
Some of the posts on here, suggest that having kids no later than the age 30 is for the best. Here's me thinking older mums were more patient too. (That's often one of the arguments for why it's a 'great idea' to have a baby over the age of 40!!!)
This thread tells a different story, as most of the mums who are 45+ and still have primary school children or teenagers (who are obviously still at home,) seem to have zero patience with them, and no tolerance for them.
As I said, so much for the 'older mums are more patient' mantra! 
yes I know this is a supremely unhelpful post, and probably a bit smug, but I am entitled to post my views and opinions, based on my experiences...
