Baby wants to know how to get his stomach

my son zhafran is now almost 4 months old, today I want to teach him on his stomach, that's why in this video I named a cute baby learning on his stomach at the age of 4 months. This is a quick way for baby to get on their stomach quickly. we have to be extra careful, because he's still very vulnerable. if it looks like a tired baby. straight to. about 1 or 2 minutes, not too long. the name is also a baby learns to be on his stomach.
