Doll Carrier The HappyVk Doll Carrier is designed to encourage the children to play and especially pretend role play. The process of pretending builds skills in many essential developmental areas. Complex pretend play are vital signs of healthy growth emotionally, socially, and cognitively. The kids can play mommy or daddy. They can also take their favorite doll or stuffed animal when playing with the other children or spending time with the parents. Instruction for using: Put the doll inside the built-in inner pocket either on the front or the back of the child. In the case of bigger dolls, the legs should be pulled out on the two sides. Assist in placing the shoulder straps over the shoulders and place the waist belt around the child's waist. Adjust the waist belt and shoulder straps, then buckle the chest strap and adjust.
