I've been fortunate to feel my babies moving since about 9 weeks, which I know is really early but one of them is at the front and the other at the back, so I think the one at the front gets a little mushed against the uterine wall!
I first felt an actual kick a few weeks ago, I wasn't sure what is was at first as it felt a little like an irritation under the skin - like when a muscle spasms and it twitches! but after I'd had it a few times and it wasn't always in the same place I was convinced it was one of them kicking me.
Now I feel them several times a day and even Chris can place his hand on my tummy and feel it, if you get a good hard kick you can also see my tummy moving.
I must admit that it's a wonderful feeling, it's reassuring for me to know they are still in there and getting stronger and it helps me to feel like this is really real this time, and that we are actually going to be parents to two little girls.
I've heard from other mums that the kicking just gets stronger and that perhaps I won't be so thrilled when I have a foot up under my rib at 4am - but I'm not going to complain! I couldn't be happier - they can kick me as much as they need to - it lets me know they are there!
