Mahirap talaga yung adjustment ni baby kasi nasanay sya sa dede nyo po. Try changing baby bottles na yung nipples nya soft na hindi nya ma distinguish if dede pba or baby bottle nya, try avent or pigeon. Tapos contact with your pedia po tanong po kayo anong magandang formula milk for your baby. I also had the same experience before nagkakasugat na yung dede ko tapos umiiyak nlang ako palagi kapag ngpapadede kaya i immediately contact my baby's pedia asking for help
