oh yes
Hermione now has her first tooth peg about 1/4 of way through and she is up all the time in the night and since around 8 weeks she has slept 7 - 7. now she wakes and cries and if you pop her dummy in she drops of. she doesnt wake crying she wakes screaming, but she is actually getting her tooth
something else i found with her is that she has the attention span of a fish - so maybe if your LO is also like this then they to may be teething.
Good luck im finding it really hard work, entertaining all day - the screaming and grumpiness and the constant waking in the night, and when its bad she refuses to drink from her bottle, but does like to chomp on the teat so the milk goes everywhere, FUN!!!!!!!!!!!!!!!!
