Once your baby can sit on her own in a high chair, mealtime becomes a party. She wants to grab the spoon, put it in her mouth, and bang it on the tray, creating her own special baby song.
Sometime in the sixth or seventh month, she may be ready to eat a cracker or dry cereal by herself. Not only does this introduce her to "grown-up" food, but it also lets her practice her fine-motor skills.
Keep in mind that even though she is eating solid foods, breast milk or formula is still her primary source of nutrition.
And remember, while it is difficult to never leave the room while your baby eats, it is important to stay with her to prevent choking or tumbles from the high chair.
