Is it normal to feel emotional

Bri • Married and mother to babygirl💓

So first off, i used to have cancer when i was younger so i never thought I’d be able to have a baby. Then i had my perfect little princess on July 26th. Sometimes i feel really emotional though, and a lot gets to me . First off , my daughter looks like my husband , and his family feels the need to bring that up 24/7. My family will say it too like “ aww she looks like him “ but his family will make jokes saying “she’s all him, she has nothing of me , etc” and it gets to me as if she’s not my baby. Then, his family will always be like “ that’s our baby, you just carried her “ 24/7 and i know it’s a joke but it really gets to me because she’s mine , i carried her for 9 months , i went thru labor . I’m a very happy person and i am overjoyed with her but i dread his family coming around because of their comments , them giving us “advice “ and ignoring what i say even though 1. I’m the mom , 2. I’ve worked with kids for years before even becoming a mom. Ugh idk it’s just weird for me to feel this way because I’m easily the happiest person in the world ... but i do have bad anxiety. I don’t think it’s ppd because it’s nothing towards my baby, it’s more with the people around my baby, and me hoping I’m giving her the best life possible .
