The baby has been very restless for the past week (he doesn't let go of his hands, he sleeps for 10-15 minutes during the day, he sleeps until 6 hours at night normally, then "the helicopter" starts with his hands so that the crib moves ? I take him - it starts wheezing, again random hand movements, kneading feet, impossible to calm down! The belly is soft... What is it? Gas/colic/weather/growth spurt?
