DD is 4, started reception in September. Model child at school, polite etc
However when we have visitors she is awful, even when it's someone she knows well. She shouts, interrupts, demands attention, is mean to her little sister. I put her in time out (at the time she does it) but it seems to have not helped change her behaviour for future visitors! I try to give her things to do and involve her, but she just carries on shouting and interrupting making me generally very cross.
Any advice or is this normal attention seeking behaviour? I'm sick of feeling like visitors must think she's an awful child and feel so deflated. She's lovely after they've gone. I'm surprised they ever come back tbh!
