They only said I should give my DS some formula because his sugars were low and as mentioned above, it's to avoid the baby going into hypo, which, weighing up the pros and cons, is a hell of a lot worse than giving a baby a little bit of formula.
If you can breastfeed immediately, OR the baby's sugars aren't low, you would be able to avoid the formula anyway.
If you do need to, I found that thinking of it as medicinal helped - after all, you would give medicine to your baby if they needed it and this was "needed" to avoid the hypo and until I could provide him with enough breastmilk.
I'm sorry to hear you have it, but 8.8 is a low result - mine was well over 12, which came as a surprise as I have no risk factors at all.
I actually tried to see it as a positive thing; I didn't balloon in weight and had lost all the baby weight (and an extra 1/2 a stone for good measure) within a month, the baby got an incredibly healthy diet (although this was more relevant as I was tested at 24 weeks), plus I have a "heads up" that I may be more at risk for diabetes in the future so I can monitor this to avoid any future health risks.
Sticking to the diet is a nuisance, but you haven't got long to go anyway. I found I had to cook everything from scratch, take food out as I could never find anything out that didn't send my readings sky high. Again, I had it really badly so you may be able to be a bit more lax.
