I could argue that it was the mantra that 'Breast is Best' that led to ds2 being admitted to hospital, with a diagnosis of Failure to Thrive (a terrifying thing to hear about your baby).
I had failed to breastfeed ds1 - as I said earlier, he had neonatal jaundice, that was severe enough at one point for him to be under two sets of lights, and I was told I had to supplement his breast feeds with formula. How could I, a new mum, argue with the HCPs who were telling me he needed this, to treat his jaundice? Even though I did manage to go back to fully breastfeeding him on discharge, I never got it established properly - he always seemed hungry, and even pumping after every feed, for 10 days, didn't boost my supply at all - so I ended up having to put him on formula.
This was in the early '90s, so way before the arrival of the internet, and the easy access it offers to information and support. I had the NCT (I hired the hospital grade breast pump from them), but no-one had any ideas on how to improve my supply.
So when ds2 came along, I was so determined I was going to breast feed him. He was born at home, and wasn't jaundiced, so there was no reason for him to need top ups.
I tried so hard - he was on the breast almost constantly, all my waking hours, or so it seemed - and yet he lost 10oz from his birthweight, and at 6 weeks old, he had not regained that - he had gained maybe half of what he had lost - I have photos of him from that time, and he looks so pale and thin, it breaks my heart.
My HV was so worried about his lack of weight gain that she came to visit me every day or every other day, to weigh him. She would tell me he HAD to gain half an ounce a day. She even, at one point, said that SHE had to think of the best interests of my baby - as if I wasn't!
At 6 weeks old, ds2 woke up from a nap chesty and wheezy, so the GP sent us to the hospital. He got antibiotics for the chest infection, but what really worried the HCPs was his lack of weight gain - that was what led them to admit him. I heard the staff, at hand over, say the dreadful phrase 'Failure to Thrive' about him - that was terrifying.
No-one did anything to find out why he was feeding so much yet not gaining weight - and the only option I was offered was formula top ups. And as it was made pretty clear to me that ds2 would not be leaving hospital until he was gaining weight satisfactorily, I felt I had no option but to introduce formula - and once I started formula top ups, that spelled the end of breast feeding for us.
At that time, there was not the same amount of support or information available - there might have been things I could have done to improve my milk or my supply - but neither I, nor anyone else I spoke to, knew anything I could do.
Looking back, when I think of how thin and sad ds2 got, before the point where he was admitted to hospital - I wonder if I did go on too long, trying to make breastfeeding work. If I had introduced formula top ups a few weeks earlier, he might not have got the chest infection (maybe he was weakened because he wasn't getting enough nourishment), and even if he had, we wouldn't have ended up staying in hospital, because his weight gain would have been OK.
It is possible that I was too committed to the idea that Breast was Best, and as a result, my child ended up in hospital.
