Diapers @
We use Mamy Poko and Fitti 360.. Used to order Fitti through the mail and it is only $10 per pack.. great value and great quality. Tried nepia, huggies, pampers etc.. huggies are always a size smaller and does not hold as much water same for nepia, which is not as absorbent as Fitti 360. The pee pee indicator on pampers is good, but we find that for newborns as they pee pee so often, the indicator is always blue meaning wet, LOL. We use Mamy Poko Pants/ Fitti 360 for days and Mamy Poko Normal for nights now. When it comes to diapers, best to try the brand for comfort and fit, drypers gave my girl bumrash often as the cover is not airy, huggies is always leaking from the sides.. but it varies from babies to babies..
When days go by, you will find that budget will become part of your consideration, and you will start dividing $ with the no. of diaper per pack as baby wet so many diapers in a day. A newborn will use up to 8 a day sometimes 9 or 10 depending on breastfeeds and milk feeds.
Do consider a good diaper rash cream whichever diaper you buy such as Desitin/ Sebamed Diaper Rash Cream..
Buying Stroller/ Sundries etc @
We swear by baby kingdom (at ubi) and cheong choon (for suppliers) at chinatown.. Combi wise, we go down to Tai Sing (Combi distributor) at north bridge. They give extra free gifts sometimes if you buy combi strollers + other stuff. Baby kingdom is the official distributor for peg perego and they usually have older models strollers up for sale at a 20% discount or more. We got our car seats from baby kingdom too- a peg perego prima viaggio and a britex both at 10% off. As for supplies- bottles, breastpump, playpen, detergents, wipes.. cheong choon is usually 8-20% cheaper..
We compared prices at Taka fairs, baby fairs.. still find more value at the abovementioned places.. Though, do consider buying in bulk to save even more
