Normal 'bad' behaviour or something more going on?

[LadyWithNoManors]

Right so asking for a friend of a friend.

DD is 4 yo and due to start reception in Sept.
Currently in nursery where her behaviour is absolutely atrocious. She bites the other children, is very aggressive, will not do as she's told, will throw things, be disruptive etc. Parents have been contacted several times.
She is also badly behaved at home though her parents allow this as they give in to her demands for a quiet life.
On top of this she continually wets and soils herself throughout the day making no effort to go to the toilet.

The health visitor has been no help to parents.
Is this normal behaviour for this age? To me it seems that there may be more to it and that the little girl is being failed as it isn't being addressed.

failed by who? her parents or hv?

It sounds a bit odd to me. Have nursery staff said anything? I know 4 year olds who don't do as they're told, some may be aggressive at times, some don't bother going to the toilet - but to have all of this going on at the same time seems unusual to me. I have a 5 yr old.

It's normal behaviour if her parents let her do whatever she wants at home. She won't know how to behave at nursery if she's allowed to behave badly at home. If they just give in for an easy life they sound a bit lazy, which could also explain her toilet accidents - if they can't be bothered to ask if she needs the toilet, make her try regularly etc then it's no wonder she isn't properly potty trained.
