I don't know what's wrong with my usually calm son ??‍? We got up at 8 as usual, and he keeps crying every 5 minutes, right tears. Then from 9:30 to 10:50 he was sucking on my breast with breaks for crying, I thought maybe he wants to sleep, will fall asleep, but no After the breast calmed down, he refused breakfast I thought maybe tummy ache, but also not really (pooped) The little tooth protruded somewhere three days ago new Now at 12 he slept for 20 minutes, and then cried through the sleep I don't even know what it could be ???
