Hello, I recently wrote that they found a cyst in the baby's head, we were prescribed Pantogam for half a month after meals, I give him it completely swallows, what should I do and don't know, can it be added to the mixture somehow? And the second question, we seem to have caught a cold? green phlegm, the mixture has become little to eat, he eats 40ml and often wakes up from hunger, yesterday there was a temperature of 37.1, to the pediatrician only tomorrow, I drip only into the nose Akvalor and suck out phlegm, then I know what to do and how to help him ?
