I used Karicare Gold as it was recommended by the maternity hospital.

I used s26 and it was great. Just the normal one though. Anything with gold on the label made him really constipated.

I breastfed and used S-26 Gold. Neither of my babies had trouble with it. All babies are different though so you may need to trial a few. Just make sure you are buying from a reputable place. Some brands, like s-26 Gold have small sticks of formula which are fantastic for starting a baby on, that way if they don’t take to it, you are only wasting $6 as opposed to $20+. The stick packs are also extremely handy to take with you in the nappy bag or when you are traveling. If you are only using formula every now and then small stick packs are perfect as large tins must be consumed within a certain timeframe once opened.

We have used bellamys organic since our daughter was a couple weeks old. She has never had any troubles with this one so we are happy 🙂
