Never mind the heads, it's the bodies that I'm more concerned about! When Josh was born, I remember how hard it was and how grateful I was to have help. I remember thinking that I couldn't imagine being a single mom, doing it all on my own.
Well, for 3 weeks, I had a taste of single mom-dom. Yes, it is do-able, but much harder than having 2 of us here and I was exhausted at the end of each day! However, I wasn't on my own for 3 consecutive weeks. Brian was gone from early Monday morning until late Friday night. So, I did have time on weekends to re-charge - something a single mom doesn't get!
I found that it was so important for me to be prepared ahead of time. After Josh went to bed at night, I would clean up from the day, get his food and clothes ready for daycare the next day. Then, I would get my stuff ready for the next day and take a shower and stuff. Only after all that, would I have time to get a bit more work done - since I needed to drop off Josh and pick him up at a reasonable hour, I wasn't getting in my full 8 hours per day at work!
On my days off (because I work 3 days per week) I found that I needed the time to prepare meals, do laundry and financials, and, since this was right before Christmas, prepare for Christmas!
I could go on and on but my point is that I admire what a single parent does. I don't know that a person is meant to raise children on their own, but given those circumstances, they do what is necessary. That, in itself, is amazing.
