My boys both went through that phase, and it's very very normal. They have growth spurts and they have growth 'lulls'. Typically they won't eat as much during the lulls, but when they get a spurt, they'll eat whatever they can get their hands on! Your one year old will probably go through the same thing eventually, but don't panic. They only eat what their bodies need, not like us adults who snack for sheer enjoyment. lol Try making him very small portions, because you can always make him more. And if he doesn't eat it, wrap it up and refrigerate it, re-warm it for later. The ziploc containers are great for leftover toddler dinners! ;)
Good luck to you! :)
PS: My youngest practically lived on mac & cheese and peanut butter & jelly his 2nd year. I don't think it's a horrible thing to make an alternative to what mom & dad are eating. His tastes will eventually change and catch up with yours.
