Appetite questions

Ok so I'm 6w2d. Since 5w0d my appetite has been hit or miss. And with my work schedule I never eat a full meal unless I'm home for the day. Now hubby is getting mad that I snack (break my meals down into 2-4 snacking periods). There are days I crave food, but eating it tends to lead to horrific morning sickness. Hubby wants me to start eating properly and at better time intervals. 
Idk what to do. Force myself to eat everything at one meal time which makes me sick or "snack" which helps with my ms and nausea. 
Btw I don't eat junk food, but healthy meals.
