Pregnant with #2

Mamas that have multiple kids, how did you handle having a rough beginning of pregnancy while caring for your first? I’m 11 weeks pregnant and stay at home mom with my 7 month old. I don’t have morning sickness but terrible food aversions that even the thought of drinking water sounds absolutely disgusting. I promise I’m not being dramatic 😩 If I could, I could go days without eating anything. I’m not even hungry. Within the past few days all I’ve had was a granola bar and a diet soda. I had to force both of them. But my energy has gone to shit! I wake up in the morning and feel like I stayed up all night. I take a quick nap when my husband gets home and still nothing. I just need to eat and get SOME energy. My pregnancy with my first was similar but not this bad. What helped you ladies? Any tips? I know a major part of being a mom is toughing it out because you have your kids to take cafe of but this isn’t healthy for sure
