16 month old, Will not sleep, is dribbling and has white spots on tongue please help me?

[didsnbump]

My 16 month old ds had a rough night last night, waking every hour.
He woke at 6am this morning, and since then has had just two 10 minute naps (will normally sleep 2-3 hours over lunch) and will not go down to bed tonight either. He has been dribbling for britain all day, going through a bib in 10 mins,he is ok most of the time but clearly over tired, and we have noticed small pale spots on his tongue.

Please some one help as we need to sleep??

Sounds either like teething or if the spots are clustered could be a touch of oral thrush easy treated by the GP.
