My 7 week old used to have a normal belly button, but (after a whole morning of straining and wriggling) I noticed it had popped out and he had a buldge in his groin. We called 111 and saw an emergency gp - diagnosed hernias. Does anyone else have experience of a belly button hernia? His really sticks out and if you push on it it squelches. It doesn't seem to hurt him, but I am worried - how on earth does it go back in and heal naturally as the gp suggests it will? Any personal experiences? He often strains for a few hours morning and night to push out wind or a poo.
