Working part time

As you know I change job recently, trying to get a job with better security and pay. Well, my new job is very nice, pays better, but I am not sure about the security part. My new company is hiring too many people (or at least I feel that way), and I am a bit worried.

Lucky for me, my old company wants me work part time for them. With babies at home, spare time is in short supply, but I do need to keep in touch so I don't lose the relationship. When I was young I used to think that I am a good programmer and will never need to worry about jobs. But now I am older and need to support a family, this is a must.
