Ermm, I agreed with Zu, best is to give plain water alone..Cos regardless its gripe water or glucose, both taste sweet. We adults might find it bland cos our taste buds already "seasoned" lai..but for babies, it is still verys ensitive, so a bit of sweet, they also can taste. So it will become a habit also...
As for me, I have been feeding my son with water ever since he is born even when he is on BM, thats why he is already used to drinking water. Maybe u can try feeding bb with water when he wakes up, cos normally thats the time they feel thirsty and will drink anything..
I tried the PIGEON mag mag cup on my boy, surprisingly, he knows how to hold and suck! But the most enjoyable thing he likes to do with the cup is pull it out and put in again..sigh..
