JE @ 15mths old

Cheers~!
Time really flies~ or zoom pass w/o we realising it ourselves...

JE juz turn 15 mths old! She weights a healthy 9.1kg on her 15mths & 1 day old. She had her MMR Jab + the 3rd pneunomoccal jab together. Her 1st jab, she was already unhappy abt the pain. Then nxt came 2nd jab & she let loose & scream out loud. She cried for ard 10min.. tears flowing out like tap-water. haha.. So the next few days was terrible for both her mummy (that's me!) & her ah-ma. She couldn't slp well in the day & night. Maybe she got frightened by the jabs. Poor gal.. & poor US!

The nurse asks me 3 standard qns on JE:
1) Can she walk by herself?
Unfortunately, the nurse tried and attract JE to walk to her, the stubbon JE refused. So this answer was "NO".
2) Can she clap & wave hands?
Yes, this has no problem.
3) Can she say simple words like Mama & Papa?
I honestly told the nurse that JE is unable to call Mama & Papa yet. All she can say is Hi-Five & Hello!

Stange gal i got right? She cant pronouce single word, but can speak 2-tone words.. "hi-five" & "har-low". Wonder wen she will finally call mama? & walk firmly to me?
