To be honest I would get a second opinion re the drugs and breastfeeding. It is highly unusual to have to suspend BF after anaesthetic after you wake up. Ring Rodney White at the Monash Medical Centre Drug information line on 03 9594 2361. Rodney is the expert on medications in pregnancy and breastfeeding. And your baby is a “big girl” now! Not as vulnerable to the effects of medications as a newborn. she should get by very nicely on food and solids while you are under sedation.
