One of my favorite meal planning tools is Prep Dish. It's an affordable subscription and they send a variety of menus to choose from each week depending on your needs: super fast prep, low carb, paleo, gluten free, etc. The shopping lists are laid out by section in the grocery store, so it makes that part super fast & simple. The menus are designed by a Registered Dietitian & chef, and once you get into the flow of taking 1-2 hours, once a week, to do your prep, meals on a weeknight take only 15-20 mins to put together & be ready to serve!

Here to echo what everyone else has suggested and add: prioritize getting help with what feels hardest for you and what fits into your budget. Sometimes baby is a great sleeper, so a night nurse isn't the greatest pain point. Finding a "Mother's Helper" who is willing to be part of the family and get involved with any type of task you need help with (not JUST childcare) is such a gift. If you end up going this route, don't be afraid to be VERY specific in your job description when you are posting online or sharing with your community about the type of person you need. Ex. Some mother's helpers may not want to help with laundry, but if that's one of your pain points, make sure you include that in your job description so the applicants you get know up front everything you are looking for. Finally, as someone who was in a mother's helper role throughout grad school, it was very helpful to know what my duties were and what they were not. Ex: I did dishes, but I did not scrub toilets - they had a house cleaner for that. Hope this helps and happy to be a resource if you need help with how to find the right person for your family!
