@WhereYouLeftIt - I think I am a little bit in love with you for that amazing post!
I struggled with BF-ing all three of mine - with ds1 I was advised by the hospital to top him up with formula whilst he was having phototherapy for neonatal jaundice - I never got breastfeeding properly going after that (despite using a hospital grade breast pump to try to boost my supply - 10 days of pumping for 20 minutes after every feed, and I produced exactly the same amount as in day1 - 4oz).
Ds2 was ebf from birth, lost 10oz from his birthweight, and hadn't regained it at 6 weeks old (despite the HV turning up daily and saying 'I want him to have put in half an ounce by tomorrow). He got a chest infection and was admitted to hospital, where the main focus very quickly became his poor weight gain - the horrible phrase 'failure to thrive' was mentioned, and we were not allowed to take him home until he had gained weight - which meant formula supplements, which in turn spelled the end of breast feeding.
Ds3 was mixed- fed from birth - BF during the day, formula last thing at night and for the night feed. As long as he had two formula feeds a day, he gained weight - if I cut out even one, he stopped gaining weight. I managed to mixed feed for 12 weeks - my personal best.
The guilt I felt at formula feeding fed into PND, and I didn't fully move past considering it my personal FAILURE until I had cbt a couple of years ago.
I look at my boys now, and can see no harm that has come to them from being formula fed. All three are strapping, healthy lads, at or over the 6 foot mark. They all did well in school, ds1 got a 2:1 in law, and has a well paid job, ds2 and ds3 are both at university, doing well.
Reading this thread, what surprises me the most is the percentage of women who don't make enough milk/good enough milk - I have always joked (well - 'joked' to hide the pain) that I clearly make skim whilst other women make gold top - and I honestly thought that I should have been able to improve my milk and my supply - I still feel guilty that I didn't somehow (before the days of the Internet) work out what help I needed, and then find it whilst coping with a new born (and toddlers) and PND. I had bought into the mantra that everyone can breastfeed, and believed I had failed because I should have done something to boost my milk.
But maybe I am in that 1-5% who really don't make milk/can't make enough milk of good enough quality to nourish a baby. Wow.
@Bellabelloo - you are 100% a real mum. You have a miracle baby, and you are doing your very best for your baby, and I am so sorry that idiotic failures in communication between HCPs have led to you being lectured on breastfeeding even once, let alone on several occasions.
