He’s got such a nonchalant attitude to illness, even if there are very worrying signs that would warrant a check up.
When DS (now 6) was a baby he had broncholoitis - I called 111 and they sent an ambulance, he was admitted for 24 hours. If it was up to my DH we wouldn’t have called up at all - he thought there was nothing wrong and I was exaggerating, despite DS clearly pulling in under his neck and ribs and fast breathing.
I do worry that if he’s looking after him on his own he’ll miss something vital.
