stranger anxiety

I have so many things in my mind that i want to share wiv hubby, but i always forget whenever i see him. So, the truth is, im now quite good at multi-tasking. If im home alone wiv bb, the pushchair mil bought is always a good help. I make baby sit in it, offer him some toys, push him to the kitchen if i wanna cook, and to the washroom if i wanna bath. No way can i leave him alone at the living hall cuz the lil boy is gonna explore the house, crawling around it, i will end up searching for him high and low.
Few days ago, i reheated the laksa my sis' bf bought from jb. Not wanting to eat in the kitchen, i brought it to the living room and ate in front of the tv, with baby in my arm. My sis who was in upstairs came down and offered help. She was wearing glasses with a hairband on her head which clearly explained that she just had her facial mask done. So i was savouring my laksa while my sis carried the baby. She then took him to the kitchen to help me wash pump. All of a sudden, i heard a loud cry. Panicked, i asked my sis what happened. It turned out that this little boy didnt see me around, he couldnt recognise my sis who was wearing glasses and hairband. So here, i concluded that my son is a drama king.
