Girls, I'm zombie?Little one has been having terrible sleep for three nights now. He doesn't cry. He wakes up in his sleep, he might cry, he might wake up. He fusses every hour? Today woke up neither light nor dawn, well-rested, cheerful child. And I feel like sand is being sprinkled in my eyes. Yesterday put him to bed an hour later, so he got up earlier. Who has experienced this, what could be the reason for these awakenings every hour? I can't even take it anymore. He fusses and sleeps. And I have to go to the toilet, eat something, or something else. Just that he fusses again on the breast?
