The American Academy of Pediatrics, WHO, and numerous other medical groups recommend 6 months of EXCLUSIVE breastfeeding, that means no water or formula. After 6 months, other foods and liquids can be introduced, although the benefits of breastmilk last well beyond six months. The WHO recommends nursing for a minimum of 2 years, and then as long as mom and baby desire. Breastfeeding can be difficult the first month or so as it is a new skill that two take part in (and one of those parties is also learning how to breathe and poop on their own simultaneously - and in a completely foreign environment to them - so quite a lot to process!). If you can get past the learning curve (and I had my own several weeks of tears and frustration), I personally have found nursing to be a very easy and relaxing way to parent my child. I have never enjoyed pumping and found nursing to be much more efficient.
I think support is crucial. If your wife is Chinese-speaking, the local Taiwan Breastfeeding Association at www.breastfeeding.org.tw
have some really lovely members. La Leche League has Chinese-speaking groups that are active in central and southern Taiwan. And finally, in Taipei, we have an English-speaking breastfeeding support group hosted by Parents' Place (I am the leader). In any of these groups, you will find moms who have been there and just want to help out other moms.
Finally, if you'd like professional help, there is a list of International Board Certified Lactation Consultants (an international certification through the auspices of the WHO) in Taiwan can be downloaded at: http://www.bhp.doh.gov.tw/breastfeeding/pdf/IBCLC.xls
. This Excel file is in Chinese but is pretty straightforward to figure out. This list was posted on the Department of Health breastfeeding promotion website on 2011-6-10, the file is called: 國際認證泌乳顧問名單. The first IBCLC in Taipei is Dr. Jean Yang at No. 424, Section 2, Zhonghua Road, Wanhua District, Taipei City 108 (near the botanic gardens). She speaks excellent English and her clinic accepts NHI.
