My son is 1 year 4 months now. He still wants milk from the teat bottle. We have tried every other cups , sippy cup, straw bottle to stop his teat bottle habit. However he drinks one sip from other bottles/cups & pushes it away & cries for the teat bottle. he has also experienced stomach infection/severe colic due to the bottle. Hence we want to stop his habit of drinking/sucking from the teat bottle. Request for your help & advice us the best process for this transition.
