It’s not a big deal OP. You’ve got to be able to handle the flak here, because people aren’t shy in letting you know if they (we) think you’re out of order. I’ve been on the receiving end, it’s just a wave you ride. You don’t need to have the thread removed, you can hide it if you like, or just shrug and take what you can from the answers given.
It’s maybe a good idea to keep this in mind for further posts - context matters, and if none is given people will go with the most likely tone of a comment. Given that for women age and being ‘past it’ is a hugely sexist, sexualised, objectifying, dismissive and infuriating notion, you really can’t be surprised that on a parenting site with ‘mum’ in the name, and a demographic whose proportions are likely skewed towards the general age you mentioned or thereabouts (or older) might take offence.
