Sewing projects

I love learning new things! 
I have one week to finish my projects and get ready to start school with Caeden.  So for the first time since moving into the 5th wheel I pulled out my sewing machine.  I'm re-covering a high chair cover with plastic to make it easier to clean... However I have come across two problems.  1. Plastic sticks to the machine and won't let it slide through. 2. If I pull my fabric along it screws up the tension and makes an ugly seam. Ugh. Oh and plastic doesn't recover after you make a hole in it the hole stays so it is super important not to make bad stitches!
I have screwed up two spots. Hopefully I can recover from that and not make any more. If I manage that goal then I could be more ready for school next week than I thought was possible.
On another much sadder note we had our first 5th wheel related injury today. I feel awful but I can't see any way I could have prevented it 100%.
Caeden had just come inside and closed the door but unknowingly hadn't latched it. Micah is pulling up on everything lately and the door is no exception. He tried the unlatched door and fell out. The second it happened my heart stopped.  I ran as quickly as possible but the damage was done my poor baby was laying on the ground outside by the time I got to him.  He has a really pretty bruise on his forehead and what looks like a scratch just above it. He didn't bleed so I don't know if you call that a scratch or what.  I tried to ice it but he just fought it off and it made him cry more so I left it alone.  He seems unmoved about it. Even fell asleep at nap time on the bruised side...I however feel like trailer trash. I am still in my pj's,  hair not brushed,  bare foot,  and my baby fell out of my trailer...guess who is winning mom of the year today? 
I'll update later on how baby is and whether the high chair cover survives my machine, but for now...I'm going to go brush my hair.
