I've noticed that whenever I lay on my side to sleep, the baby will kick really hard. I actually feel his feet on my right side, so if I lie on my left side (as recommended), he kicks really hard. I wonder if his head is on my left and if I'm squashing him? When I googled it, some people mentioned they had this because their babies were transverse. I haven't had an u/s since 20 weeks and not sure if this is the case.

If you had a transverse baby, how and when did you know? And did you have this issue lying on your sides?
