Girls! SOS! A small toy accidentally fell on the child, it wasn't painful, but we got scared. Now we are afraid of every rustle for two days, we almost don't sleep all day, we cry and refuse to hold hands, we get angry, we don't take sippy cups right away, first we have a tantrum then we take sippy cups, before we used to sleep for two hours calmly, now we sleep for 20-30 minutes during the day, what should I do? I don't understand, I am also having a panic attack, what should I do? ? help??
