Empowering mothers worldwide through connection, support, and shared experiences ✨
Moms commonly take calcium and vitamin D for as long as they're breastfeeding and iron for around 6 months; for knee pain, they advise avoiding cross-legged feeding, keeping legs straight, doing gentle stretches, and getting calcium/vitamin D levels checked.
⚠️ Caution:Get your calcium, vitamin D, B12 and hemoglobin levels checked if pain or weakness persists, and see a doctor or orthopedic for severe knee pain. Take painkillers only as advised by your doctor.
Moms worry their knee and leg pain signals a lasting problem and are unsure how long to keep taking supplements. The community reassures that this pain is common - largely from feeding posture and depleted calcium - and improves with posture changes, stretches, supplements and proper bloodwork.
Here's what moms in our community shared based on their own experience.
Many doctors suggest calcium as long as you're breastfeeding and iron for about 6 months; some moms continue prenatal tablets to at least 6 months postpartum. Get your calcium, vitamin D (and if weak, B12/hemoglobin) levels checked.
Knee pain is common and often comes from posture - folding/bending the knees while sitting to feed and from missing calcium. Avoid sitting cross-legged (one doctor advised not for the first ~2 months), keep your legs straight, and sit in a chair while breastfeeding when possible.
Do gentle stretches for all the leg muscles and yoga, and take regular walks - these help with time.
Eat a calcium- and protein-rich diet. If pain is severe, see your gynaec for tests or a good orthopedic; use a painkiller like Dolo only if truly needed.
Even some moms taking iron, calcium and vitamin D still get knee pain, so posture correction matters too.
