Dd grabs my face

[Daddyg123]

Hello I am a new adoptive parent to a Dd , she is a good sleeper eater and genuinely lovely. I am so blessed but she has taken to grabbing my face hard when she's frustrated or doesn't want to do something . It's mainly me but has started to be others to . I try and stay calm and explain that it's wrong and if re occurring use the naughty step . she's only two so I'm finding it hard . Is this normal or should I be worried . Any advice is welcome !
