I felt mine when I was about 22 weeks, this was due to my placenta being at the front, when I went to the midwife appointment they warned me that this could result in me not feeling the baby move as much or struggle to feel anything at all!
About 19 weeks with my first and about 16 weeks this time. It's all very exciting isn't it? Once I realised I was feeling movement I realised that it had been happening for a little while! I thought it was just wind.
Thanks everyone! Size and Moo I can definitely feel a similar sensation and your posts really made me laugh. I've been trying to work out if it was just the feeling of stretching, but it definitely feels like little flops! Crackles I heard that the second was easier to feel (or at least easier to recognise?) so it must be true! It is so exciting.
