What influence your decision in buying diaper products?

For starters, online review is the way to go to get an idea. Afterwards, start trying out the different brands on your LO. If buying a whole pack of diapers for trial and error seem a waste, you can actually request for sample to try. Why? Because babies comes in different sizes, what might work for one might not for another. We tried and decided upon a specific brand of diapers based on material, absorption and the dimension.
