I am 28 weeks pregnant with my 2nd baby (first was a caesarean as he was 10 pounds) and I had a scan last week. He is feet down (feels like he is breakdancing on my bladder) and the placenta is low. I feel like he is stuck there and he is also big already - 2.2 pounds. He has been in the same position for ages although he is very active. Should he be changing position more or might the placenta be blocking this? Any advice on how to get him changing a bit more?
