It's not good to let them sleep under Sakiz. She may squish or suffocate them. Is the box they are in big enough so they can be next to her. Taking them to the vet isn't recommend until they need their first shots at about 8 weeks - check w/the vet. The kittens immune system is still to new to fight off all the germs at the vets office.
You should leave food, wet and dry near Sakiz and move her litter box close. She will not want to go too far from her kittens the first couple of weeks. She will need a lot of food. You can even feed her a little of the yogurt.
Keep an eye on the 3rd to make sure he is gaining. If you have a scale you can weigh them everyday at the same time. 10 grams or more is a good weight.
Glad to hear things are going well. Keep us update.
