My dil went back to work this week and I am taking care of my 7 week grandson. She has been gone 10 hours a day and left 4oz, 3 oz, and today a little over 1 oz of milk. I think he needs an ounce for every hour she is gone. She has a hospital grade pump from WIC but says she has no place to pump at work. That means she isn't pumping or feeding for 10+ hours. She sleeps with him and nurses all night. She breastfed their 3.5 year old for 2.5 years but she didn't go back to work until he was 10 months.
My son, grandson (the baby's brother), my son's two brothers, and I all have a very rare immune deficiency disease called Common Variable Immune Deficiency (CVID). We all have allergies. His brother has had head to toe eczema since he was an infant and has food and other allergies. All of us except his brother have asthma. His brother will probably get it with as bad as his allergies are. This baby must be breastfed and shouldn't get any formula.
So far he is gaining very well (better than any of my 3 or his brother), is chubby, is having very wet diapers, and I'm changing several diapers with stools during the day. That's why I'm not in a panic. My son recognizes that something should be done, she doesn't. If she won't pump more milk (she may not) should my son try and get milk from the milk bank in California? He handles all the kids medical issues and could get a prescription. Should we try and get local milk? The baby needs IgA and I'm not sure what freezing does to IgA. Local fresh milk may be better. Since he will get most of his milk from his mother it may not be an issue. We may need about 40 oz a week.
