St. Patrick's Day Birthday Corned Beef and Cabbage, carrots and Potatoes

My daughter Marina's birthday is on St. Patrick's day so we enjoy this Irish meal on her birthday to celebrate the occasion. Here's a simple easy recipe I like, and it needs to be simple for at this very moment a 1 year old baby is toppling a teapot over while perched on a stool with her sister who is precipitously leaning onto the kitchen island trying to reach a tea strainer to-do-I-don't-want-to-know-what with it in her smoothie! Here's the recipe:

Brisket of corned beef (2-4 #) Ours come with herbs on top (chopped bay leaf, black pepper kernels, red peppers
1/2 head of green cabbage
4 carrots chopped in half
4 potatoes quartered

Put corned beef in large stew pot and cook for at least 3 hours at a slow boil. Four hours is good. Add carrots and potatoes 35-45 minutes before serving and cabbage 15 minutes before serving.
Serve with crusty bread and/or side salad
