Ay alam ko yan, ang bula talaga ng Nido is annoying! A few of us tried different ways, may kaibigan akong ginagamit ang fork to stir it really gently instead of aggressive mixing, at may isa pang nag-try ng mainit na tubig muna bago ang powder, tapos very slow stirring lang, at talagang less bubbles talaga. If your baby's rejecting it because of the bubbles, you can also try letting the milk sit for a minute or two after mixing bago ibigay, para naturally mabawasan ang bubbles, or gently scoop off the top layer, nakita ko rin yan sa isang mommy friend and it helped her baby drink mas masaya!
