Girls hi! Baby when he takes a breastfeed a couple of times and cries with legs kicking and pulls at his chest with hands and loses his breast. And so like 10 times Do you guys do that too? Maybe it's not getting enough? I feed him breast milk on demand and with formula twice a day (30 ml in the afternoon and 30 ml at night Nutrilon) How often do you give formula in our age? If on mixed feeding.
