Err no, Cats. I really cannot imagine you are as dim as you are trying to make out. DD did not become ill because some of you get upset about the odd biscuit - that is facetious.
It is about people giving babies/young children unnecessary foodstuffs and then people like you guffawing about those parents being all 'PFB' about it. Parents not wanting their children to eat certain things, (no matter what may or may not have happened in the past) have a reason for their children to not eat certain things. And as it can, at times, be life-threatening, it is not helpful for someone like you to think it is just one big hilarious joke. Comments like 'How are you doing in PFB land' are vacuous and unhelpful, and, dare I say - rather insulting.
My DD didn't have an allergic reaction to a biscuit, it was something else, which is beside the point somewhat. The fact remains you DO NOT give a baby or very young child (who cannot speak for themselves) something to eat without first checking with their responsible adult. In this particular instance, a seven-month old baby would still probably be in the weaning process, so no-one in their right mind would offer a foodstuff, when only cuddling the baby for 10-15 mins. For someone else's baby, it could have been the banana containing a potential allergen. Again, you are missing the point, thinking this is a bit of a non-issue about a baby being given a bit of a biscuit to suck on.
And to anyone saying "The mother should have mentioned any allergies". At that very young age, a mother might not even be aware of any potential allergies or intolerances. Weaning is done in a controlled environment.
You give your own children all the biscuits you like - don't give them to other people's babies without first asking and then 'LOL' about it in 'PFB Land' when an allergic reaction occurs.
It is your attitude that stinks, IMO.
