perhaps also try the cold water lay down thing. I dont have anterior placenta thing, but, it does work for me, from about 20 weeks on.
Drink a large glass cold cold water fast as, and lay down. Sometimes, i have something sweet to eat as well. Apparently the combination of the cold water, sugar, and sudden inactivity wakes baby up, so, i like to do it before i go to bed at night.
DH is only just starting to feel bubs move now.
Oh, only really had a few 'butterfly' like feelings as well..Most of the feelings i got earlier on where more like 'chuggs', similar to that when you need to go #2, but have been hanging on for ages. KWIM?
