at what age does a baby sit up
What age do babies start sitting up. Most babies begin learning to sit up when they are four to seven months of age as their motor skills start developing gradually.In the third and fourth months, the head and neck muscles start gathering strength, helping the baby to raise his head and hold it in that position during tummy time [1] .n between five and six months, your baby usually starts to sit up with your help, holding his head in an upright position, keeping the back straight. He may even be able to sit for a second or so without taking any assistance from you, before toppling down after a while [1] .
