oh hun, DD is just 2 and went through a phase of totally hating DP for about a week, was terrible! would let him near her, and would just shout ''i hate you daddy, get away from me'' but we tried really hard not to make a fuss and it passed.
Different to your situation but maybe its just a phase, she is pusshing boundries and learing that she can control things. no real advice....il think about it! hope you get some good advice!
