My dd, only 4 and a half is already telling me she hates me - this is almost entirely when I dont let her do something (for reasonable reasons) or if I (rarely) do something accidentally that inconveniences her.
So also attaches to other rlmen sometimes eg the other Mum on a play date, or a female friend of mine she needs and is super affectionate, starts calling them Mummy, starts saying she wants to live with them etc.
Shd does the same to her Dad (hate you stuff) but not the calling other women Mummy ie other men, Daddy.
(She is generally very well looked after, gets most of what she wants, a lot of effort put into taking her places, doing child oriented stuff, we're affectionate parents, not sure about my husband but tells me she loves me a lot etc).
The above behaviour can be embarrassing with other Mums/friends... but it's also a bit hurtful, even though I usually successfully tell myself she's a 4 Yr old child.
How do you deal with this?
