At 2 months of age, your baby should be having 5 - 6 very wet diapers every day and regular, substantial bowel movements. Average weight gain during the first 3 to 4 months is four to eight ounces per week. Even mothers with very abundant supplies sometimes worry whether or not they are making enough milk for their baby. If your baby has been healthy, gaining weight well and has good output, you can rest assured that you have plenty of milk for her. If you think your milk supply has been compromised, expressing your milk, using a hospital-grade electric breastpump with double pump kit, between 6 and 10 times every 24 hours, will quickly help to build your supply.
Some moms find it convenient to pump following nursing.
This rich hindmilk can be used, instead of formula to supplement your baby. You did not say how much supplement you have been using each day. Nurse your baby before offering her any supplement. This will allow her to have several feeds a day where she breastfeeds exclusively. Remember, she should be nursing at least 8 to 12 times a day.
