Girls, help me with advice. The baby is one month old, we're plagued by colic. It starts in the evening and lasts until morning on the hands, crying, sleep for 15-20 minutes at this time. We did an ultrasound of the head everything is good, we visited pediatricians, neurologists, they say the child is healthy, all is well. You have colic. I give biogaia in the morning 5 drops and Espumisan 3 times a day 25 drops. And they also said to keep a diet. Is it really possible that the diet helps? How can I help the child?
