While mastitis can be treated quickly, it's best to avoid it altogether. To try and prevent it, health experts recommend if possible, to opt for exclusive breastfeeding and avoid supplementing with formula or using dummies. You can also feed regularly and encourage full feeds to prevent a build-up of breastmilk. Try to ensure your baby latches on properly to avoid irritation and consider different positions to increase comfort. Gradually reduce feeds when stopping breastfeeding and avoid tight clothing or bras.
