Since 20 month:
1. Can relate different word with same meaning.
Eg: mama=farah, ayah=baba=papa=abah, pakcik=adik, makteh=kakak, tok=mak, balqis=batrisya=tisya=balqis batrisya=qis
2. Start to explore new alternative doing thing.
Eg: nak ambil barang jatuh bawah meja & capai dengan tangan tak sampai, she will take other things untuk capai benda tu or nak ambil benda on high cabinet or table, she will take anything such as cushions, small chair or box for her to climb up.
3. She can play masak-masak & pondok-pondok with her teddy bears with set periuk I just bought.
4. She can partly dress herself - try pakai stokin, kasut, seluar & baju by herself.
so far as I remember that's all. nanti kalau teringat lagi... I'll update again.
