"Hi Aliya, thank you for your greeting! Did you get H1N1 vactin for yourself? I got for my daughter and myself. I was difficult in the beggining of breastfeeding, I was doing both bf and formula for the first month. If your baby is gaining weight, try to breastfeeding only or reduce formula. But I recomend both way is good for both you and your baby just in case when you need to take a rest or babysit."
