Girls crying out of despair?

Girls crying out of despair ? The baby started gurgling and cooing while feeding, he also does it with the bottle, then when it's time to hold him upright he burps, that's how it is, mommies, dear ones, have you had this experience? I'm very worried that we won't gain weight ? We haven't been to the clinic yet, as they cancelled our appointment because there were sick children there.
