Little bit of background - my daughter's preschool shut unexpectedly in December so Jan she started a new one.
A few weeks into term I asked the teacher if I could have a few names (first names) of children my daughter plays with to invite to her party (she is 3 turning 4). The teacher initially said yes then the reception advised they are unable to even give out 1st names due to data protection and advised me to ask my daughter. Unfortunately my daughter has a slight speech delay and having not long started also doesn't know the names. In the end I just sent blank party invites and asked the teacher to place them in bags of who she plays with. Not many have replied maybe because they weren't named on invite specifically.
Now I have slightly older children at a different school and there school will give you a class list of 1st names only for party invites/Christmas cards.
So AIBU -
Unreasonable - my school won't give out 1st names
