Now, let me explain why it was important for Nathan to have this exact sippy cup.
This Avent sippy cup was recommended by his speech therapist for two reasons. First, the liquid dispenser (part of the cup that goes into his mouth) is very similar in texture to his bottle nipples - this can make the transition from bottle to cup easier. Secondly, see those handles? They're removable - so, the cups can grow with Nathan.
