Nixie,
Have a look at his tongue before you feed again... If it's still white, then ask at Chemist or MCHN, or DR...
Indah kept pushing her tongue out too, like she was itching it... Luckily my nipples are fine, but I read it can cause them to hurt, sting, burn etc...
But I dont seem to have that!?

Indah now weighs exactly 4kgs, so she has gained about 500gms since birth, she has 3 chins.... =D> hee hee!
