How can I help my baby learn to sit up?

A. You can use four or five pillows at one time once your child completes the time of six months make your child sit with support on the bed on the bed rest and put a pillow behind the back then one pillow on the left and on the right or two on either side and one in front of your child on the legs because the child usually gives a leg straight one or two pillow on the legs of the child so this with the child is going to be tightened up and will get a good grip to try this start from at least half an hour one time
