No wine or any alcohol until the infant is at least 6 weeks old. Prior to this their liver is too immature. Best bet is to express & bottle milk prior to drinking and/or wait at least 6 hours after wards for feeding.
If you are only drinking a very small amount, say with dinner, then you won't have any problems. If you have several drinks then you are better off bottle feeding as some of the alcohol can be transferred to the baby. In many cases the baby won't even like mom's milk after drinking alot.
I wouldn't. Anything your drink while breastfeeding will go directly into your milk stream. Basically anything that you consume your child does too. Alcohol isn't great for your baby. You could drink ONE GLASS and it wouldn't really do anything but I always like to be on the safe side for my child's sake.
No, Never do like that..... because people need your care and love. nursing means care people with your love, sincerity. and simplicity.. people like that thing.
