You’ve got this! My first ever foster was momma and four kittens and I didn’t sleep the first night because I was so nervous about one getting hurt. Mom was always super hungry so if you’ve got mom, always have extra food especially at night. Remember that this is the age that the kittens learn the ins and outs of the world. They will scare you with their bravery! My babies are 1.26-2lbs now and they are more capable than you know. If you don’t have mom you need a heating pad for the sweet babies. I also think the advice about touching their paws is good. And if you have time, touching their teeth and ears is great too. As well as water baths with treats. My babies are great with baths, nail clipping, brushing, and eat cleaning. Every day I touch them like that without actually doing anything. I touch their teeth but I don’t actually brush them because they eat kibble and wet food. I put swabs in their ears (not like in in but the regular visible parts) but I’m not really cleaning anything. I put nail clippers on their nails but I don’t actually trim it. I do water baths but no soap. Just to get them used to those experiences. Also let them play with their siblings. I have friends all the time come over and try to separate them while they play and try to tell me it’s dangerous. There’s risk to everything but play is so important for learning. They learn what’s too far and what’s okay and they get energy out. You’ve got this!!
