He's had a virus for about a week (rash, cough, fever) which we've been treating with parcetamol and ibuprofen. I think his big problem is that he needs a poo (I can't remember when he last went, but I'd guess at least 4 days). He is farting quite a bit. Is there anything we can do to make him poo? Are the meds causing constipation? Is it possible he's eaten something (I've never seen him eat!) that's upset him? Help me make him more comfy - please?
