It's not just about how many wet nappies, it's about how wet they are.
I was one of those mums who believed so fervently in breastfeeding that I refused to believe that my baby was in fact getting malnourished- despite the HVs repeatedly raising concerns about her weight. I kept assuring the midwives that the nappies were wet; I had no idea how wet is wet. I'd read all the books, I had oodles of milk and dd was latched on correctly: how could anything possibly have been wrong?
What was wrong was that dd was actually too weak to suckle: in spite of my having had extensive latching-on instruction in hospital and further instruction at home by midwife and healt visitors. I was doing everything correctly, but even the best latching on in the world doesn't help if the baby isn't sucking.
We ended up in hospital and it was a long hard road to turning dd round, through syringe feeding and an exhausting programme of expressing and discarding and breastfeeding and expressing.
11 years later I found out that the reason was probably hypotonia, caused by dd's genetic condition.
But the warning signs were there and I was told. The hospital staff and the health visitors have nothing to blame themselves for. I have.
Because I had convinced myself that if you choose the best way and do it correctly nothing can go wrong. Like heck it can't!
