Any movement is good movement

or at least thats what my MW kept telling me in my 2nd trimester as i was worried that some days the movements were stronger than others, it really got to me!
Apparently as they still have enough room to turn in full cirlces etc at like 20-30 weeks legs and arms dont tend to stay in one place for long so just as you are getting used to its movements, it decides to turn over and have a dance about! naughty little people hehe!
Be assured though that in 3rd trimester they stay put a lot more especally at the end and the patterns are a lot easier to reconise. I remember panicing loads on like 2 daily basis' about babys movements lol! they like to keep us on our toes!!
