My 13 month old is sick. He has ulcers all over the end if his tongue, a red raw throat and very red ears. No pus. He is on panadol and nurofen alternating but can't get to sleep without a minimum half hour meltdown (he is so tired though) and isn't taking liquids. I stocked up on sugary crap squeeze pouch yoghurta, custard, fruit boxes but he's probably only had 50ml all day...any tips for getting him to sleep better And get fluids down?
