I am now 25 weeks and I've been feeling lots of movement for ages, getting stronger and with more definite patterns. But I've heard somewhere that it's possible to tell which 'bit' is making the movement and that helps you guess what position the baby is in. I did feel a hard raised lump which I thought might be a head, but when I pushed at it a bit it gave me two punches back (!). Does anyone have any tips on recognising which bit is which?
