Teething at 11 weeks old

Michelle
I have a beautiful 11 week old son who is teething. The doctor said he has quite a few coming. He is so unsettled bless him and won't let me put him down when he is asleep, he only sleeps at night. He has raynaud's and a temperature of 36.8 which is not shifting even with calpol. I feel for him so much, I've also given him bongela but nothing seems to ease him. Any suggestions.
