crying in his sleep...

[Hoping]

...Thomas has been sleeping through the night for some weeks now (although sometimes wakes at about 5am for cuddles and snuggles!).
When I say he sleeps through, he does not feed at night any more. But he does seem to cry out intermittently, about twice a night and when I go in to him, he is asleep but thumping his legs and crying. I hold his hand and speak gently to him or give him a dummy and he goes back to peaceful sleep.
Does anyone have any experience of this? Could it be that he is going to break a tooth soon? I hate to think he is having nightmares - it happens every night.
Thanks!

Could be teething. Lately Grace has been crying in her sleep and she is cutting new teeth. She went to bed at 7 and I have heard her cry and go back to sleep 4 times already!
