Letting the baby use a fork/spoon helps develop his motor skills and hand-eye coordination. Of course, they need tons of practice to get the hang of it. Nonetheless, using utensils makes the baby feel included and more encouraged to eat!
We are using the fork and spoon from @eztotz and love them.
They are perfect for little hands and have a little barrier to keep the baby from gagging! Make sure to choose silverware that isn’t too heavy and your forks aren’t too sharp. It’s safer for the baby to use. Keep in mind that there’s no rules in buying utensils for baby aside from I’ve suggested before, just to keep babies safe.
