DS is 12 days old. Lost 13% birthweight by day 3 within severe jaundice. Had phototherapy treatment and 2 hourly breastfeeds and is putting it back on although very slowly (still 6% below birthweight today). I am giving top ups after most feeds on instruction from the midwives. Top ups are EBM as want to avoid formula. DS refused them in a cup so have been syringe feeding but midwives now want me to give more than is recommended via a syringe. If I introduce bottles now will it screw up feeding forever? His latch is still not great sometimes and I wouldn't describe bf as established yet.
