U should be confident that you'd be able to breastfeed your child.

Don't worry on the low milk thing, many young mother give up as the early stage there'd be very little milk being produced. My wife had the same problem too, but we both never thought of having formula milk as 'standby'.

6 months in my girl is now strong and healthy being breastfed on demand by the wife. Should u need help u should join the Facebook group called Malaysian Breastfeeding Advocates. A lot of good advise there.

HOWEVER back to the question, what's best for baby according to my paed in SJMC;

1. Similac
2. Wyeth S26
3. Enfalac
4. Avoid Nestle!

Formula fed babies do have constipuation problems so do be careful before u decide to even 'mix' it up a little
