Oh my gosh, bless you and I wish you all the best. Sorry, no pointers here, I am just a Mommy to the precious malts.
But my heart and prayers are with you.
Have you ever looked at you tube seeing Maltese being born. Some of the videos show the actual birth. There was this amazing couple's video, showing every step of the birth, but I can't find it now

. As each one game out, they put a little colored yarnish looking material, and each one got their own colour so they could tell them a part. As a Mommy, not sure I would do that, as I would worry, that they would chew at each others yarn, but I now zero about breeding.
Do a search on you tube. Not so much for showing you what to do, but it is amazing to see how they are born.
Keeping you in my thoughts!!!
