Hello everyone! Girls, who used to use something during teething? We have all symptoms of teething, already three days eats little, appetite is gone completely, during the day as usual, but at night everything starts: restless, can't fall asleep, doesn't want to lie down, only on hands and then only vertically. Snot flows constantly, sucks fingers and gets angry, cries. What can I help my son with? Thank you all!
