Hai, memang normal je untuk toddler usia 2 tahun makan dan minum lebih banyak sebab dia growing rapidly, metabolisme dia memang laju! My friend's son was the same, minum banyak sikit and she was worried, but paediatrician kata it's just part of development. Tapi since your little one memang active, energy bagus, and sleeping well, I think you're good lah. The full nappy in the morning is actually a good sign, means he's well-hydrated. Just keep monitoring ja, if you notice dia suddenly becomes lethargic, or minum excessive sangat beyond what's normal untuk age dia, then boleh check with the doctor just for peace of mind. Otherwise, sounds like a healthy growing toddler to me!
