My baby is in mixed feeding both mothers milk and formula, as soon as I feed her, sometimes she passes urine and demand again for feeding within 20 to 30 mins . but this is not happening with formula milk. Is this sign of insufficient mother's milk?

A. no dear not at all it does not show that the breastmilk is insufficient breastmilk is almost 90% water so baby may pass urine immediately or even during feeding good urine count indicates good feeding it is also easily digestible so breastfeed babies may feed more frequently Ideally baby should only be breastfeed exclusively till 6 months complete it is nature's complete food for baby
