Does using a waist cushion for too long have an impact on the baby?

Patient's question:

No

Doctor's answer:

Ready to use right after birth. When holding the baby horizontally, use one hand to support the head, place the baby's waist and buttocks on a stool. Around three months, the baby becomes sturdy enough to face forward, with the upper body leaning against your chest and shoulders, and the buttocks supported on the stool.
