Well for PJs I have managed to get hold of the following patterns
Simplicity 5382
Simplicity 9499
Now whilst the boys require jersey for the top, I still have room to play with flannel for the bottoms!
So plans:
Step daughter 1 : long PJs : Top Material : Bottom Material
Step daughter 1 : long nightie : Material
Daughter : long nightie : Material
Son 1 : PJ : Bottom Material : Top 1 (sleeves) : Top 2
Son 2 : PJ : Bottom material : Top 1 (same as son 1) : Top 2
