How To Treat Flu In Infants And Which Contraception Pills Work?

Hi, I have 2 questions. Firts my baby of 2 months is getting the flu,what can I give her?
Secondly I would like 2 know if u think I should see a specialist? I have tried a few of tHe contraseption pills and it doesn't accomodate with me. (Get most of the symphtoms and my period last for 3months) with both my children after the C-section my uteris didn't want 2 pull back and the dr had 2 give me something so I can stop bleeding. I then went for the 2month contraception injection and now I had my period for 4 weeks. What should I do?
