Firstly asampras well done for trying breastfeeding!!
The first few weeks are hell and very worrying, but in a few more weeks you will look back smile and be glad you carried on.
I breastfed my son now 12 years and am now breastfeeding my daughter of 13 weeks, both times i was close to giving up, the latchin on, constant feeding and worrying how much their taking really takes it toll.
But im happy to say i can do it now with my eyes closed!!
it just takes a liitle practice and patients, but im sure it will get easier.
If your demand feeding your baby will be getting enough, in the first few weeks i was forever shoving my breast in my baby's mouth!!!
She was 7lb 14oz at birth and now at 13weeks weighs 15lb 12oz, so im sure she's getting enuf!!!!!
things have settled nicely now, i feed her every 2-3 hours during the day, she would go longer but it helps the nightime feeds stretch out to 4-hours if im lucky!!!
Don't know if that helps, but good luck anyway and even if you do go on to formula you have still given your baby the best start
