Just adding my 2 cents. From my clinical experience, there is no contraindication to giving liquids (using the generic term) infants under 4 months of age with a cup or spoon. In fact, even premature infants can be taught to cup feed. Far better to use this technique if there is a concern re nipple confusion or appriopiate technique for cleaning (cups and spoons are far easier to clean than baby bottles:)! Now, I avoid giving solids/beikost via spoon to infants until 4-6 months of age (and of course never ever by bottle!). Somewhere around that time they are less likely to do tongue thrusting out of solids. Of course I have had patients and known of other babies that did not "get the hang of" taking solid foods until much later (8-12 months).
