If you want to learn parenting skills, small-step early education is still very credible. When I was a baby, I didn't even dare to touch it. Fortunately, teacher Xiaobu taught me all kinds of parenting skills and learned to take care of my baby scientifically. Now the baby has just reached the full moon, gained more than three pounds and is eight centimeters long. He can put his head back on his stomach for 20-30 seconds, and when the kinetic energy reaches 180 degrees, the follow-up reaction is also very fast. .
