Find out what baby items are stocked in local shops, eg which nappies and size, which formula (if applicable), which wet wipes, Calpol and such. No matter what we did, we always managed to run out of something fairly important that we needed ASAP!
Stock up for your own recovery. Antenatal services don’t tend to highlight anywhere near enough about postpartum recovery. Even with a fairly straightforward vaginal birth, you need recovery time and some stuff can help. I recommend buying plenty of maternity pads (with wings if you can find them, helps them stay in place), witch hazel (to sprinkle on the pads, nice and cooling), plenty of painkillers (I say get cocodamol in, you can buy over the counter, as well as regular paracetamol), Anusol (loads of pregnant women and new mothers get piles, better to be ready with some relief). And just take it easy. Give yourself at least two weeks to relax and see how things goes when the time comes, but don’t try to run around, play host, tidy and clean etc. I’m not saying no visitors, but focus on having visitors you’re comfortable with, who won’t care that you don’t get up to greet them or make them a cup of tea, who you’re happy to sit with in big comfy clothes, no attention to hair or make up, half dozy because you’ve been up throughout the night. People who just love you and your baby, who want to say hi, maybe even bring you a meal (bonus!) and then will leave you in peace after some newborn snuggles and an easy going chat.
