Ah @Colourbeari understand how you feel, hugs to you.
My DS has a noticeable birth mark on his face between his eyes, it was v bright but also started to swell after about 4 weeks. So every day, wherever we went, at least one person made a comment. More people would stare.
The staring got to me more than the comments. I could respond to comments, people who stared never said anything so I ended up just glaring at them until they felt embarrassed and stopped looking at us.
When people did ask me, I was able to say in a breezy voice:
"Oh no, nothing is wrong, it's only a birth mark <tinkly laugh> he's gorgeous isn't he"
and effectively force the nosy and rude person to agree he was a gorgeous baby. Which he was. He had a perfectly round and chubby wee face and a cracking smile too.
He had to be put on medication (propranolol) as it got very large. It flattened out entirely and the colouring faded a lot by 18 months. If it hadn't swollen to the shape and size of an egg we wouldn't have gone for the meds.
He is old enough now to see it and because we were nonchalant about it, he is now too. He tells me if other kids comment on it but he tells them it is just a birth mark and everyone just moves on.
You will start to notice it less, or just see it as part of your baby's beautiful face, in no time at all. And other people will bother you less, I promise x
