Mummydreamer- I didn't really feel bub regularly until about 24 weeks I think, before that I would feel very occasional movements but only really been in the last 3-4 weeks that they're strong movements and coming all the time.
I think Alan was saying that MW like you to be able to feel 10 movements a day but he says not to start charting that until 28 weeks as before that a lot of the movements can be too light to feel and you end up panicking over nothing.
I'd say if you are feeling bubs at all that's a good thing!! Too early to be worrying about number of movements.
