My strength is leaving me, the baby is three months old, he's screaming, nervous, holding his hands in his mouth, all his face is red until I am not there with fists, saliva runs out. I carry him on my arms for 20-30 minutes quietly, then he starts crying and so he gets nervous, that even his breast doesn't take, in sleep we go out with tears, he hasn't pooped for two days, clean on Gv.
