princessxiaomei,
I'm not sure if it's sweet cos I din really compare with other FM. I give him, he drink, so I just continue, cos he wasn't really eating well at one time. But now that xrisgoh mentioned that it is indeed sweeter and causes phelgm, I may consider changing after he finishes this tin. No wonder he drink since it's sweeter.
kaira,
His first tin also vanilla. Then now second tin, hb bought wrongly, bought strawberry, he also drink. Before this, he was on bm. Actually, he still is, but I'm cutting down his reliance on me.
