Thank you all for the replies! I feel reassured after reading most of what you've said and I appreciate all the kind words. I think it's just the mama bear in me honestly..
I dont have anxiety disorder or mental health issues, thank for! It's a bit peculiar of people to assume that, by me just being a bit inexperienced in some parenting areas and having certain concerns.
I have fear of insects, since I've known myself, it isn't normal perhaps for most people, but I'm sure every person has some fear. I try my best to overcome this, and have up to a certain extent, but I still don't find the idea of bugs crawling on our heads appealing. I'm sure no one does, for me it's just a bit extra extra. If it comes to this, I will deal with it, regardless of how I feel.
I had never thought about homeschooling, as I want DS to have a normal social experiences. The comment about 'my fears limiting my child' is absolutely groundless. I just wanted to hear if that's the way it is and it does seem so.
Changing nurseries idea stems from the fact that there are other options, generally speaking, private nurseries etc. But from what I understand the situation is the same everywhere.
As to being in contact with germs, yes I agree, thinking reasonably, that is indeed how children build their immune systems. I'm not afraid of germs, I do encourage my son to get dirty outside. We jump in puddles when it's raining, he jumps on piles of leaver in the autumn and does snow angels. We've got lots of plants at home and he helps when repotting for example, needless to say it turns into a muddy game in the end but it's part of childhood.
I'm not, in no way, saying my child is more special than others, as someone suggested. It's just that I personally would keep him home if he was ill. I understand that's not an option for a lot of people and I acknowledge that, yeah, coughs and runny noses can persist long after infections or viruses have cleared up.
Perhaps I am being unreasonable.
I grew up in Europe. When I was a child, lice was a pretty rare occurance, in my parent's childhood it's been much more common for example. Nowadays I honestly have no idea, I've been living in the UK for many years and abroad before that for some time. I haven't thought of looking that up, until it slapped me in the face the other day.
Where I'm from nurseries are very different to UK nurseries in many aspects. There's no meaning in comparing. We live where we live and we will adjust to the current conditions, one way or another.
Sometimes our expectations of how things should be, does not match reality. In the end it is what it is. It's never too late to learn something new, and I've learned a lot today.
Seems that I do need to toughen up.
Thanks for the heads up on threadworms.. I have heard of this but also wasn't aware it's that common. Note taken on probiotics, Ovex, nit comb& gin! Will make sure to keep these readily available at home. Better safe than sorry.
I understand how some people might have found my post offensive. Most of us have lives outside of children- work, school, maybe both and more on top, I know I do, so we can't keep our children at home on a whim. Surely at the same time all parents want their children to be healthy and well. I didn't mean to undermine anyone. I apologise if I have.
Again thanks to everyone, for taking the time to reply xx
