Girls, can you please tell me if our teeth are already erupting? We have saliva and fists in our mouths for about three months now. But starting on Monday, the baby has become very capricious, sleeps very little during the day, but wants to sleep constantly. I thought it was the tummy, but the tummy is soft, does his business several times a day. I attached a photo, the quality isn't great, but maybe we can see something ?. Thanks in advance for the answers!
