There are a bunch of threads here with this topic, as many of us are moms. I know for me, I really had to figure out what my priorities were and what I could allow to slip through the cracks. My house, now that I've graduated, is a complete disaster, and I am slowly getting my way through it one project at a time. But my son (age 5) still loves me, I did very well in school, I have a fantastic job offer (once I pass the NCLEX), and my husband and I survived.
Time management is huge. Make it all count. This will likely be exhausting, honestly.
Figure out what works for you for studying. For me, I HAVE to leave the house. HAVE to.
Figure out how you will manage your stress. You NEED something that is just for you to decompress. For me, it's running. Find a way to fit it in, as this MUST be a priority.
Meal planning. 'Nuff said.
Large cooler. Carry your food with you to school, clinicals, study sessions, whatever. This will save you money and calories, and will save you time trying to search for somewhere to eat. That said, get a registered Starbucks card, because you'll be earning those stars and earning free drinks. Yup.
My husband and I text each other every little thing that comes up, like when he meets with the dog trainer or a customer, and I tell him when I'm meeting with my study group or am volunteering with my son's school. We each have our own way of tracking our calendars (him on his computer, me on a paper planner), so a quick text allows us to get it in where we need to. We also have one in the kitchen that we each update every couple of days with everything going on.
I try to study with my son, but it's hard. Sometimes we'll read together outside on our porch, but this is usually for a much shorter period than I really need.
Carry study materials everywhere. Everywhere.
Rally up the troops. A friend you can call if your kid is sick and your SO has to be at work. Someone who you can call and cry to when you're on the verge of a breakdown. Someone who can fold your laundry. Whatever help you can get.
Schedule a date night with your SO whenever possible.
Schedule a day at the beach/park/whatever with your kid when you have a slow moment. Even just a couple of hours of fun makes a difference. For this, ignore my rule about carrying study materials everywhere. This also applies to date night.
You will likely feel like the "every other weekend" parent (or at least I did), in that you make every moment count by doing fun things when you're together and feeling like you're absent for everything else. Be honest with your kid. I've held my son and told him how much I miss him when I'm at school and how much I wish I could be here more. I think that honesty helps him to know that I'd love to be with him more. I have also kept him abreast to how much longer school is and such, and give him things to look forward to. I also keep my word.
Tuck your kid in every night you possibly can. This is a special time that we don't have for much longer!
