I wasn't allowed to get my ears pierced until I was 13...same rule for my daughter - now 25...she was VERY happy that we made her wait...SHE got to make the decision instead US making it for her. I wouldn't have done it and I think it's wrong of you to do it when you discussed it and he said "no" - you thumbed your nose at him...VERY disrespectful in my book.
You and your baby's daddy need some serious counseling...you are sooo not on the same page it's not even funny!!
You guys are keeping track of each other's shortcomings instead of learning from them and putting them behind you.
He SAYS "ONE DAY" he will take his daughter on his bike...okay- ONE DAY. Girl - stop!!!! You two need to get on the same page...that's all I can say...co-parenting or not - you two need to grow up and stop trying to do stupid stuff behind each other's backs or one-up-ing each other.
Get counseling ASAP and learn how to communicate with each other and make MATURE decisions about your daughter's welfare TOGETHER...you did this baby together - now you are stuck with him for the rest of her life...there's a reason they say don't have babies out of wedlock...yes, I do know that many marriages fail and children get the short end of the stick...but its NOT the child's fault!
