Try asap. my baby had no nipple confusion at all. We introduced the bottle at 1 week old and she had gladly took to both bottle and breastfeeding. it wasn't until she was hospitalized at 2 weeks old for more than a week where I only breastfeed and when we were released, she no longer wanted the bottle.

You should introduce 1-2 weeks before going back so she is in a comfortable setting to learn something new. Make sure to use a nipple that is similar to breast.

@wiccanmommy, she's doing really great tho that's why I'm sorta confused.

Depending on how well baby is doing at the breast I would say 4-5 weeks post pardum
