Are you in the UK? If so, look up the baby academy as they do free online classes including one about bathing, changing, feeding etc - it’s very helpful!
Take baby classes like breastfeeding, baby care, child birth and etc
It'll all come more naturally than you think practice making a bottle closer to babies due date or do research on breastfeeding so you know how to. Practice doing a nappy on a Teddy lol!
have you take any classes to just ease your mind at all?? i’m also 30 weeks and while packing my hospital bag i just felt so underprepared so i understand where you’re coming from. i have a few classes scheduled over the next month so im hoping that makes me feel better.
