L.S.
Congratulations!! I also have a 3 yr old (4 on 2/24) and a 16 month old.. It is very hard to find something they both love. I read a lot of the mom's ideas which were great; however I shop on a VERY tight budget and try to penny pinch every chance I get... My best idea for lunch is Chicken Pot Pies - kids who hate meat (my 3 yr old) will eat it because of the gravy and kids who hate veggies (my 16 mo. old) will eat it because of the gravy!! AND if you buy the ones that you heat in the oven they are less than 50 cents a piece!!
Good luck and best of luck on baby 3! girl, girl girl girl girl
