Girls, who are on IV or SV, you have these fits due to bloating, gas and so on from the mixture. Mine straight up goes off, it's hysterical even shakes it. It puke with screams, shits through the day at best. Now I put microlax, without them can't go, screams horribly ??‍♀️ We are on SV and since birth, these fits from the belly. Pediatrician is silent, like this is normal. Who did something? Baby drops, eспумизан, dill water, massages and so on doesn't help. In general, has anyone had this way??
