My baby was born early at 35 weeks and was in NICU so I never established BF'ing. I pumped every 3 hours in hospital with wonderful results. When we got home pumped regularly with continued great results.Unfortunately, sleep won out. I haven't pumped in a week or two. How do I know if my milk is dried up and if I can get it back. I feel horrible as my breastmilk supply has finally run out and it seems he is not tolerating the formula well. Any suggestions will be apprecaited.
