Your baby can start straw training with StarTouch Drinking Cup which promotes healthy oral motor development and has an easy-to-sip straw which encourages natural drinking. The cup is spill- and leak-proof too, which makes it great for outdoors! However, as every baby has different likes and development pace, we have different products to cater to their different needs. If s/he has some difficulty to progress from Teat to Straw, you can let them have a step-by-step transition starting with SofTouch Training Straw (6M+), and then progressing to SofTouch Drinking Straw (12M+). They are created to provide similar feel to SofTouch teat while training the baby to progress to straw drinking. StarTouch Adapter & Straw Set can be purchased at a later stage, for outdoor usage.
