Revolting, this will be my first child, and I know I'm not experienced in this, but I am willing to bet that you are a fantastic mama. Parenting is not easy, and there will be days for every mom/dad where they feel like they're not doing a good job. But ya know what? No one is perfect, and that's ok! I'm positive that you're a great and loving mother to the kids you have, and that you'll be just as amazing to the new baby. Big hugs to you lady! Keep your chin up :)
Yogini- That sounds like what I had today. Just really tight feeling, and very hard uterus. So odd!!
Em, How far are you? I bet you did feel a kick! And yay Shiloh for feeling kicks! I love it!
I started feeling kicks really early, like 15 weeks. They just felt like tiny muscle twitches at that point, and slowly turned into stronger twitches and pokes, and now definite movement. My husband and I both felt our first kick on my belly on Mother's day when I was 19 weeks.
