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!
I am exactly the same as you and also need advice 😫
I made a list of what to pack as I went through the daily routine so broke up the list into sections, waking up, eating breakfast, naptime, bath time, swimbag, travel/nappy bag etc and then put everything needed under each section. Do this with enough time that you can go out and buy enough of the things you need for each section, such as wipes, nappies and Calpol.
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 😉
