Baby sleeping TOO much?


My babe is 5 weeks old and it seems like the last 2 days she’s sleeping around the clock! She has like an hour of awake time in the evening but other than that she wakes up to eat for about 30 minuets every 3 hours and then she falls back asleep! It’s new so is it just a growth spurt? She’s not sick. Eating just fine. I have terrible anxiety so I worry about everything 😖 Anyone else’s baby do this? She’s sleeping like 18-20 hours a day still!
