Breastfeeding is best for babies but if you have decided to switch solely to formula feeding, you can do this at any time. However, if you wish to combine breastfeeding with formula feeding it’s best to wait until breastfeeding has been firmly established before introducing a bottle (or if your baby is over six months, they can use a beaker or cup). Whatever option you choose, introducing formula will lead to a decline in your breast milk production – a process that is very difficult to reverse and can be an emotional decision to make so give your body & baby time to adjust to this new change.
Slowly reducing breastfeeds by one feed a week will give your body time to learn to produce less milk. It will also prevent your breasts from becoming engorged or leaking. If they feel full to bursting, expressing a little milk can help relieve the pressure.
