Hi , pls share with me what type of beef can I cook for my 18mo?

You should go for a lean cut. Top sirloin steak will be a good Choice. Choose organic beef or grass fed beef if you can. These are better than corn fed beef. You could also give ground beef to baby. You can purée beef with sweet potato for a health tummy purée which is easily digestible. Or you can make pasta with ground beef bolognese. Remember to cook the beef right through. If you are into baby led weaning you can make beef finger foods for baby too. Try making beef meatballs with spinach.

I gave ribeye steak at medium well. She took it well and asked for more. I made minced beef in homemade tomato sauce over pasta.
