I am glad that I found this. I posted the same question/kind if post a few days ago, and no one will respond.

My curls got looser, and bigger after my DD was born. She was born almost 2 yrs ago. It takes more effort to get my curls to look right. My curls stay close to the head. I nursed her for 18 months. I didn't stop until after I found out I was pregnant with my son. It became uncomfortable to nurse and I was so sick. I am now 24 weeks pregnant with him.

I think it is because my hair hasn't had a chance to "be" on its own. I have went from pregnancy to nursing, and back to pregnancy, with no break in between. I will likely nurse DS for at least 2 years, so it may be another 2 1/2 years before I can see if my hair will go back completely. Lol

I just wonder if anyone else has had this happen?
