ds has had a temperature since wednesday eve it varies but 38.6 seems to be the hottest its got, he's about 37.8 now but always seems a lot hotter at night. He has no other symptoms but is bit clingy and lethargic, he does have moments of play for 15mins or so occassionally and will still laugh and babble occasssionally such as if i put pingu on tv. He's had colds before but this is odd, just a high temperature. Was only feeding him at night but have reverted back to constant suckling the last couple of days as this soothes him. should i be worried? have given him some doses of calpol when i thought he felt very very hot. And am keeping him in. what is too hot for a baby (over 39c? or 40c?)please advise me! 1st time mum!
