We never know since they may not like to drink juice like wing wing. first time you can use 1 oz (means bottle juice not fresh one) and mix 1 oz water to see what happen.
Car_pretty,
yes, 用奶樽餵, but you can try to the straw put into the 奶樽. Remember the first time you give juice to Nam Nam, must 溝浠 to see whether they can digest or not. if there is no problem for two to three times, then may not need to 溝浠
