Yes, but you should start off by mixing 1/2 pediasure with 1/2 formula first.
Can I Give Pediasure To 6 Month Old Baby?
Not now but you can feed him/her with pediasure after 6 months when he/she will become an year old and that time you can feed him/her with pediasure without any worry as it is a complete and balanced nutrition for the growing children :-)
