He did stop. He's fed and is sleeping now. I called the maternal, child health nurse who recommended panadol, which he's now had.

we've had some unsettled behaviour before with wind etc, but this was even more so. We'll see how he is throughout the night. He doesnt have a fever and the injection site isnt red or raised. The screaming started this afternoon, not straight after the injection. It could be mixed with his normal evening unsettledness/wonder week/wind. He was alert between crying fits.
