Hi mum, you don't need to bring baby along for your own postpartum check-up at KKH as they'll be focusing on you and your recovery. Most mums I know just arrange childcare at home or ask a family member to watch the baby while they go, since the appointment is usually quite quick and straightforward. Just call KKH ahead to confirm if there's anything specific they need you to bring or any forms to fill out beforehand.
If you have someone to look after, you can leave your baby with the caregiver. I did not bring my baby along during my post partum check up
