Chelsea is now a bit over 7 months and her sibling is due in 15 weeks. I have noticed when she is with kids her age, younger or older, she turns into a real bully, Poking eyes, pulling hair, trying to bite, pinching etc.

I understand she is young and learning new things and exploring... but im worried she will still be doing this by the time M2 is here.

She obviously does not understand what no means or my explanations why she cant do something just yet... but how do i tell her no now so it doesnt keep happening? Or is this normal and i should just not worry about it?

When she does something no i sternly say NO and stare right at her and she just laughs and keeps doing it....
