Milo does the head burrowing and rubs his face up against me when he's tired, regardless of whether he has a cold etc.

I give him panadol if he has a high fever or if I think he's in pain.

Like, last thursday night he was crying way more then normal at bedtime and really unsettled. I tried offering him a feed but he wanted none of it. I ended up giving him panadol.
On friday, he got weighed and had not put on much weight at all, and that night I gave him a formula feed and he went off to bed with no probs, so I spend all of that night and saturday feeling like I'd given him panadol when all the time he was just hungry...

Then on Sunday morning I find out that he's just cut his third tooth, so now I feel less guilty. I think we just need to elarn to trust ourselves.
