Working mom of 3 children

Having three children is hard especially when you're a working mom. I am afraid that they will feel unloved because I have no time for them. What can I do?
Hello, @elusivescorp thank you for the reply. I am not usually spending time with my kids during the weekend especially if I have deadlines to catch up. A note on their book is a good idea; I will try it out. I am planning to take them somewhere when I can make a leave. Where will be the best place?
