HELP!!

I don't know what to do, come bedtime Olivia screams the house down when we put her down. She is happy as larry to go to bed any other time by come 7:30 and she screams and screams. I go in there, she throws her dummy away and laughs, we let her cry for awhile to see if she will just settle but it gets worse and worse DH is in there now, she is quiet but we put her to bed at 7:30!!! This is just a pain, especially when we have ppl over for dinner I don't know what to do.

A lot of the time she still has wind, now this is after giving her her bottle 1 hour before bedtime and its only 50ml more then her 2 day bottles (200ml at night.

I am out of things to try...after about an hour or so she eventually drifts off. Tonight I have given her nurofen (as she is teething) but she is never this bad with teeth. Argghhh pulling my hair out!
