Double edged sword (this is a half praise/half complaint)

My SO got up with our 5 year old and they made breakfast. And he asks me how many pieces of French toast he should make. And I tell him.....and he doesn't do it. Because he's making eggs.......he's the only one who will eat eggs. So then we eat. And I get up to make more. And he gets mad at me! Because "I don't appreciate everything he does for me" I did say thank you and was very glad he made breakfast (he does it every Saturday. It's the only morning he's home) but he's mad.....because me and our son are still hungry...because he didn't listen to me, when he asked a question, and didn't make enough. I love that he makes Saturday morning breakfast. And he knows that, I tell him all the time. I'm pregnant. And our son is 5. What pregnant lady and 5 year old eat one slice of French toast and one piece of bacon???????
