DD is very nearly 4 yet her speech is 90% incomprehensible to anyone but me and her siblings. She has some behaviour issues too and I've been trying to have her referred to a paediatrician for these. On Monday she came out of nursery and had the biggest meltdown of her life. When she calmed down later she mentioned that she doesn't like nursery; she said everyone (adults and children) ignore her because they can't understand her 
I emailed nursery that evening explaining what DD said, asking how they're finding her speech, asking how she is there generally and detailing some of the behaviour issues to see if they've seen anything similar. They haven't replied. DD was supposed to go today but didn't want to and they haven't enquired why she isn't there which they usually do if she misses a session.
AIBU to think this is poor form and to feel like not sending DD back there?
