What are you stressed about? Make a list of what baby will need, and what you need and then pack it as you go and tick it off.
Start making a list for you and a list for your daughter. I think sometimes the most overwhelming part of planning is the thought of it. Once you start making a list then I think you’ll realise that It’s not that overwhelming. Then put the suitcase out and pack a few things every day and tick them off your list. Again, it won’t seem like such an overwhelming task then!
As long as you have a bank card and not going to middle of nowhere, you'll be fine, babies are everywhere, which means whatever you forget, you can buy locally 😉
