I work in a year2 class and some of my pupils need to wear deodorant now. It baffles me how some parents are unaware that it's not good for a child to wear the same polo shirt all week in this weather, or that sweaty armpits need washing more frequently.
When a child throws their arms around you at 9am and you can smell sweat, well I can't help but judge the parents. It's unavoidable.
My son started wearing a natural deodorant in year2,in year4 we had to change it-phew!
I have taught all five of my children hygiene basics,ensured they have clean clothes, have access to deodorant and know how to use it.
They will never be the 'smelly' ones. Two have left home,but they still maintain what I have shown them-lifetime skills.
The ones who don't have this, will no doubt go on to be the adults we read about on threads who find their partners abhorrent at the stench/hygiene.
All because no one has taught them. Makes me very sad. 
At my school we have superb pastoral care,and children have been brought uniform, shoes,had them washed by staff and deodorant purchased for them.
If I was in an older class,I would definitely make up a parcel of ST, pretty soap and deodorant and give them out as prizes etc. Couldn't live with myself if I didn't.
Feel so sad for some on here whose parents didn't ensure their basic hygiene needs were met.
These things leave scars. No one wants to be the smelly kid
