He usually poos every 2-3 days but now hasn't pooed since a mammoth session last Monday. Everything else seems okay - lots of wet nappies, generally bright and cheerful. But he does grunt and strain a lot and has evil smelling wind. He's also feeding more at the mo which I assume is a growth spurt.
Should I be concerned?
(btw I put this in this topic because I assume it is linked to bf in some way)
