boy or girL

Today.. mami, san yie, khu-khu and I go to the doctor again.. it's our 3rd visit.. this time we go without papi.. mami told me that papi is working.. mami and i must be patient and wait for papi.. before coming here, mami did the medical check up for control mami's thyroid.. Doctor wants mami and I always be healthy..
Now i am on the 12th weeks.. I grow up to 3,9cm in healthy condition.. on my age now, i have hair, nails and voice... so that when i born, i will cry loudly..
Papi told mami that i am a boy.. coz papi said if i am a boy, i can take care of my younger sister and brother.. and papi can guarantee that i am a boy.. coz mami changed a lot when mami is pregnant now.. Mami's behavior is not like usual.. mami felt more lazy and sleepy all the time.. but mami said.. wheather i am a boy or a girl, mami still love me..
I am still too young for showing papi n mami if i am a boy or a girl..
