Begin by dicing the beef, carrots, potatoes, and onion, and mince the garlic. Ensure all pieces are small enough for easy chewing.
Heat the olive oil in a large pot over medium heat. Add the chopped onion and garlic, sauté until softened (about 3-4 minutes).
Add the diced beef to the pot and brown it on all sides (about 5-7 minutes).
Stir in the diced carrots and potatoes, and cook for an additional 5 minutes, allowing flavors to meld.
Pour in the beef broth and add the green peas, thyme, and bay leaf. Bring to a gentle boil.
Reduce the heat to low, cover the pot, and let it simmer for about 30-40 minutes until the vegetables and beef are very soft.
Before serving, taste the stew. If desired, add just a pinch of salt but remember to keep it minimal for babies.
Remove from heat, discard the bay leaf, and let cool slightly before serving. You can mash it gently for an even softer texture or leave it in small bites for toddlers.
