When I found out I was pregnant last month, I went from 2 cups a day to 1. But... the last few days I've been backsliding

. I have a 2yo and 5yo and rarely get a good nights sleep due to medical issues with the 2yo. By 4pm, I am having sooooo much trouble staying awake. Anyone else drinking more than a cup a day? Fwiw, I fill the mug with 1/4 coconut milk, 1/4 whole milk, 1/2 coffee and some cocoa powder - so it's not really a full cup although we have large mugs, and I only drink water the rest of the day. Trying not to feel too guilty while also hoping some of this exhaustion goes away 2nd tri.
