There's nothing quite like the feeling of becoming a parent for the first time. As your pregnancy progressed, you were likely counting down the days until you were able to experience all the incredible new-parent firsts you had heard so much about: seeing your baby open her eyes for the first time, her first coos, first smile, first laugh. And of course, nothing can prepare you for the deep, unconditional love you feel for your little bundle.

But as rewarding and exciting as first-time parenting is, it can be challenging, too. If you’re a new mom and are feeling stressed, guilty, exhausted or all of the above, know that you’re not alone. Being a parent is hard work — and for most people, adjusting to this new role takes time.

Below, 14 moms in the What to Expect community open up about their experiences as a new parent, plus the most difficult thing they've had to get used to as they adjust to motherhood.

”[The] hardest thing is the lack of sleep.” — JayBee25

”The fact that I'm SO tired by the end of every day... Sometimes I feel as if a truck had ran over me. That said, I also feel so much love. More than I ever knew I could feel and that makes me feel so happy and fulfilled.”  — anacaro00
