Actually you can continue to use step 1 until 1 years old... in fact I use the steps as age... so when age 1... i use step 2... and age 2 change to step 3...

To me it is the affordability... step 1 is so expensive now... that if you can cope... do give step 1... coz usually step 1 has higher and better content that step 2....

Dont worry bout taste so much... but do worry if it is sweet... you wouldnt want your baby to have a sweet tooth when they are so young...
