I will be 17 weeks tomorrow. I have heard that you will have days when you do not feel the baby as much as other days. It depends on your baby's sleep cycle. Your baby may sleep more when you are awake... your activity during the day can actual "rock" the baby to sleep. =) That's pretty cool, huh? You could try drinking a glass of milk or juice and then laying down, I've heard after 20-30 minutes you probably will be able to feel the baby move shortly after you drink or eat. I wish that I could feel mine ALL DAY long to make sure everything is OK. Somedays I do not feel pregnant at all but my growing belly helps to make that feeling a reality. Remember that your baby will likely sleep around 12 hours a day.
I am 23 weeks....how far along are you? is it normal not to feel the baby move all the time?
How far along are you? I am having what is called Round Ligament Pains... you can google it and find tons of info. Those are really scary because sometimes it is hard to tell it they are "cramps" or just the "growing pains" of our uterus.
