Breast is best but in my case, not so much and baby is very healthy with no health complications. My intentions were to breastfeed after giving birth but her 4th day of life, it just wasn't happening. Pain- bad latch and inadequate milk flow. Lactation consultant helped during my 2 day stay in hospital and everything seem to be going well but. I had a good pregnancy and favorable delivery all natural but just couldn't get the latch correct. Spent money on 200 pump and still just not bring enough milk. I'm back to work and in my case formula works best ......God is great!
