Thank you to everybody that has commented on this thread - it has actually been very helpful.
First of all, it was a genuine question about seeking people's views as to whether it was the norm these days to sanitise with hand gel before picking up the baby - absolutely no problem with hand washing but I think he believes that santising with hand gel is better.
When my children were born hand gel hadn't been invented well at least not available in the public domain and although it is normal these days when visiting a hospital or care home, etc, to sanitise, even a cruise I went on there was a hand gel dispenser at the entrance to the restaurant because of the threat of norovirus spreading, it was quite a surprise to me when he said that he was applying this regime in his house - I just hadn't heard of any of the young families of any of my friends doing this.
The overall opinion is that he is probably being ott but just go along with it and he'll probably relax after a while. Very happy with this feedback and have no problem and happy to go along with it. Was just interested to know current thinking.
I posted very early this morning because we went out for a day trip to France and was quite amazed on our return a short time ago at the amount of discussion this has generated. Just to put everyone's mind at rest there is no falling out - I sent a txt to my daughter telling her we were at a French hypermarket stocking up on hand gel which she took in good humour.
But I wouldn't mind making some comments on some of the views expressed here.
First of all, I am not a grandmother but a grandfather. I don't think I made any gender references but I suppose people just assumed I was a grandmother because I posted here in this mother's forum. The reason I posted here is because it is the most relevant place to pose my question particularly as there is thread especially for home childcare and the majority of you are mothers so the best people to ask.
Yes, some of the comments were a bit barbed such as the poster who thought I was looking for ammunition to support my side of the argument which wasn't the case, I simply wanted to see what the overall majority thought on this issue and I am persuaded by the reasonableness of the majority of the comments and it has helped me take a different position to where I started from.
I must say though that 'EverythingsRunningAway' was pretty spot on at reading between the lines of my post. The son-in-law is a bit ott over everything and this was just the latest. It wasn't put to us as a polite request as such but as a demand and it was more the delivery of the edict that resulted in the heated aspect of the conversation. He hasn't gone as far as demanding face masks yet but does want a change of clothes and shoes off (and no, we are not smokers).
Also I acknowledge that the thread title was a bit of an exaggeration but it was the best I could come up with at 4 in the morning that would catch people's attention.
btw, none of us have dogs but we do have two cats but they will probably run a mile when our daughter brings the baby to visit.
Once again thank you to everybody that commented - it has been very helpful.
