Place your baby in a high chair with a tray at the right height (your baby should be able to reach the food with his hands). You’ll need a spoon to offer the puree (and a damp cloth to clean if necessary!).
Then, to ensure that your baby has a positive experience and wants to repeat it, make sure the atmosphere at mealtime is relaxed. Offer him a first bite by putting a small amount of puree on his lips. If he closes his mouth or nods “no” with his head, don’t insist and postpone the experience to another time.
If you favor a BLW (baby-led weaning) approach, you can also simply place a pre-filled spoonful of puree on his tray. Your baby will be able to experience this novelty by himself, which is beneficial for developing his senses (touch, smell, sight, taste…) and for promoting a healthy relationship with food.
