Girls are hard! Harder than boys. I didn't know such a thing to be the case until she turned about 9 (going on 25)! I have a twentysomething son but he was NEVER a challenge to relate to.
1. Love her like she likes to be loved
It is very hard for me to hold back affection as I was raised in an affectionate family but my daughter doesn't like overt displays of affection (I think she has a bit of ADHD or is on the edge of a neurodiverse disorder ~ if I used that incorrectly someone please let me know in the comments). But through effective counseling I have come to see that I should not take this personally. Rather, I should allow her to define the hugs and kisses. And when I am smart and do not pressure her or push myself on her, she invariably comes to me wanting affection. It sounds creepy upon a second reading but I am being sincere about the relationship and nothing weird.
