your bb's time for drinking (15-20mins) is OK. And I don't think Nuk is a problem. According to my pedi, Nuk's design is best to let bb keep their mouths close tightly.
wait until 3 months-old (or may be a little bit longer), and one day you'll suddenly find the problem gone. my girl used to throw up each time she took the milk until 3 month-old.
i don't know how old is your bb. Mine is also like this until 12 month. I am so frighten when i feed her every time because whenever she vomit, i am so busy...comfort her, change her cloth, change my cloth, clean the floor, the chair,etc. But she stopped vomit after 12 month old, maybe the valve between the esophagus and the stomach is fully mature and close properly by that time.
So,now you may try to feed your bb bits by bits and let bb "ur" air more frequently.
Don't feel sad, always think that things will be better later.
hym2005,
Spilling almost happens to every baby, however (噴泉式嘔奶) doesn't happen to most of the babies. It is caused by the immature of the stomach's valves (which opens and closes when baby drinks). This might also cause baby to have colic. Have you taken your baby to the doctor yet? If 會噴泉式嘔奶 happens very often and spills quite far away e.g. > 1 meter . Then it is necessary to seek medical help.
Here are a few things parents can do while taking care of this type of spilling.
(1) burp baby often during the feeding time.
(2) direct breastfeeding is preferable due to bottle feeding leads more air into the stomach. Also, 小食多餐 is recommended.
(3) lift up the cot legs (the head side), then the milk won't flush back easily.
(4) Maybe colic medicine needed if it is related to lots of crying.
My baby is also like this from 9 months (after flu) until now - 16 months. Before, he's doing fine. I am very worried & nervous. He vomits very easily, either drink the milk or eat the congee. I was so upset about this. Same as szeszes, I always prepared a plastic cup nearby when feed.
I've seen quite a lot of different doctors, all said he's ok. But he's very slim after 9 months.
