You may also notice that your baby has a wiggle at his temples as he sucks and swallows. To encourage an abundant supply, allow your baby to satisfy both his sucking and his nutritional needs at your breast. I would not recommend using a pacifier at this time. Nurse at least 10 to 12 times a day. Allow your baby to finish the first breast offered, coming off on his own when he is relaxed and satisfied.
Some babies are happy nursing at one breast per feed, while others want to nurse at both breasts.
Watch your baby, and follow his cues. If so, you will probably need to supplement with either your expressed milk or formula following a few of his feeds. I would not recommend supplementing after each feed. Allow several feeds each day where he is nursing exclusively. It is important to find out the cause of your reduced milk supply and preserve the breastfeeding relationship, while safeguarding the health of your baby.
