If you had a straightforward vaginal birth, please allow 1 -2 weeks post-partum for breastfeeding to establish and breast engorgement to settle; as massage can increase a release of toxins into the breastmilk or cause mastitis if lying on the breasts for too long (although a pregnancy belly beanbag can still be used for support).
Even if not choosing or successfully able to breastfeed; the hormonal levels still need to adjust to enable milk supply and breasts to stabilise.
If your baby was born by caesarean or you required manual removal of the placenta under anaesthetic, it is recommended you wait until after your 6 week post-natal checkup, to obtain medical clearance.
If you had a vaginal Birth with post-partum bleed, requiring transfusion or iron infusion; allow at least 2-3 weeks.
