I'm so happy to hear that things are a wee bit better! As for teething, I do believe at this age you are OK to give meds. I would stick with tylenol. My Dr. said that she likes to put some ibuprophen (sp?) with it, as it reduces the swelling, so that's what we do. So, that being, Advil, Motrin, etc... I've been using the Hylands Teething tablets, that you find at a health food store, but I haven't had great success with them, but others swear by them.
Have you talked with your Mum and made it pretty clear about not stimulating DD in the middle of the night? I find that my parents just kinda' tune me out b/c they figure they've raised kids and did just fine. KWIM?
The other thing I was thinking about was whether or not DD has a been introduced to a soother or comfort item? These two things are SAVING OUR LIVES right now. I would just suggest that you two don't run to DD right away when she wakes, just give her time to try to settle on her own. I know sometimes that I think I've given my LO enough time and it's really only 45 seconds.
HTH,
Allison =)
p.s. keep up the good work Dad! Letting her sleep is very kind.
