Now that I've started my own family I've incorporated this same tradition with my children. In fact, pajamas on Christmas Eve was a tradition in my husband's family too! In years past, we've bought our kids PJs, but this year I decided to make them. And let me tell you, it was so simple! Depending on the size of the PJs I could get 1-2 pairs done in an afternoon while my son took his nap and my older two were at school. I loved doing this so much, I even made a fourth pair for my nephew.
For the basic pattern I used this pattern and tutorial from danamadeit.com. I printed the pattern out (it's sized for a 3 year old) so for the other sizes, I used an existing pair of pajama pants to make the pattern longer/shorter. I found the waist size and the leg width to be good for the sizes I made: a child's 6x, 4T, 24 months, and 12 months. The waist size was good because once you add the elastic for that specific size, it will cinch up to the right size.
First, print and cut out the pattern and tape it together. If you're making a size bigger/smaller then have a pair of pants on hand to see how much bigger/smaller you need to cut the length. TIP: leave PLENTY of extra length for folding the waist over and hemming the bottoms. You can always cut off excess later. If you're making a pair for a larger child that needs extra width on the pattern, just use your existing pair of PJs as a guide and trace around it. Just be sure to give yourself extra room for sewing your seams. In my case, I always give myself LOTS of extra room... I tend to sew pretty wide seams.
Since these are lined, you'll need to cut out a set of front and back pieces on white flannel and a set of front and back pieces on your patterned flannel--so you'll have a total of 8 pieces cut out (or 4 sets). Again, if you're making you're own pattern look how the original pattern has a slight angle on the waist of the front pieces. This gives the pants a better fit.
