LO is 9 months old, has a top tooth trying to come through.

Her sleep is horrible! She used to sleep 6-8 hour chunks, but hasn't in a long time, but the last few nights have been wretched. She'll go down around 7:30 and sleep 3 hours, wake for a bottle, and then usually go down for a few hours, wake for a bottle, repeat. For a while she was waking at 10:30, 2:00 and 5:00.
Last night she was up every 45 minutes to an hour. Sometimes she wants to eat, sometimes she needs a little teething gel or her paci, sometimes she's just grouchy. She doesn't just fuss a little, but wakes up shrieking. I finally got up with her at 4:00 and let her play in the living room so that DH could get some sleep. She played for an hour and a half before falling asleep for an hour, then awake again.
Why? What can I do? I miss sleep! DH needs more sleep. She needs to get more rest.
