Hi Karen,
The oldest baby that we helped to return to breastfeeding was 13 months. A 12 week old can learn to breastfeed again.
What bottles are you currently using? We've found that the AVENT system with the newborn (1 hole) nipples can help to get baby back to the breast. Short stubby nipples should be avoided as they do not encourage a good latch.
Since it's only been about 6 weeks since you last breastfed you can try re-lactating without the birth control pill. Domperidone would help to increase your supply but if you live in the US you'll have to bring it in. You can find it at
www.globaldrug.tv. But please let your doctor know what you're planning so you can be monitored.
The starting dose for birth moms is 10 mg 4 times per day before meals and at bedtime. Then after about a week, you can increase to 20 mg 4 times per day.
The MOST IMPORTANT thing you can do is contact an international board certified lactation consultant (IBCLC) to assist you with breastfeeding. You didn't mention why you stopped. The IBCLC can help you to overcome any number of concerns. You can find an IBCLC near you at this website
www.iblce.org Just click on the "About IBCLE" button and the US and International Registries pop up.
There are several videos on our site that may help you as well. Just click on the "Breastfeeding" button and scroll down to "Video Clips".
A good double electric breastpump would help you as you rebuild your milk supply. Most of the mothers on this site have been successful with the Medela Pump in Style. I've used it to induce lactation twice myself. The Medela Lactina Select also works well. The idea is to pump 8 times in 24 hours but do what you can. If you can get your baby to the breast with the help of a nursing supplementer you may not need to pump as often. You can find one here
www.lact-aid.com The idea is to feed baby at the breast which stimulates your own milk to come in. Then pump when you can. It takes work in the beginning but you can do this.
Warmest regards,
