Same age sila ng baby ko pero masaya na ako kapag nakakapag "papa papa papa" siya minsan. For me it is not unusual for their age since every child is different. I have four kids and iba iba sila. Yung 3rd child ko mama lang din nasasabi paminsan hanggang mag 2 years old. But still, if you have doubts, ipacheck mo na mii.😊
