Catface don't worry, I was exactly the same! A week before DD was born I was holding my friend's tiny premie baby and paranoid that I would drop him or break him or not hold his head properly and it would fall off. I had next to no experience of babies and was not a 'baby person'. Before DD was born, I had never even changed a nappy! I had to get a midwife to show me how to do the first one in the middle of the night!
It's scary and you're clueless and with a very few exceptions everybody is the same. But you know what? You will learn and it will get easier. And if this group turns out like my last one, it converted to a fb group and I asked loads of questions and got loads of advice and things to try even in the middle of the night when everyone else was asleep, there was always someone up feeding too who could help.
So, try and give yourself a break, it's completely normal to feel scared and overwhelmed as this is one of Life's really big fucking deals but there are loads of people out there to help share the load and keep you sane. Big hugs lovely and try and not put too much pressure on yourself x
