This varies greatly between babies and changes as they grow. Rather than focusing on specific amounts, watch for signs that your baby is getting enough: Appears satisfied after feeds, wets 6-8 nappies per day (with or without stools), shows appropriate weight gain on growth charts, has alert periods between feeds. For newborns, remember their stomach is tiny - just marble-sized on day one, growing to ping pong ball-sized by week two. Feel free to approach your paediatric feeding speech therapists to find out more!
