Can anyone help me my Daughter is 4 months old now when will she be able to go into her jumper?

when they can hold themselves up good is when they can start in a jumper. you can do tummy time. or practice sitting up (if baby can hold his/her head up)

My son is almost 3 months. I just bout him those mats with the toys that hang. He loves it. @kaylabeth1994

What else can she do, I'm new at this.

Okay.

when she has total control over her head
