I agree with @trippinsaputos, it's not so much about having to 'allocate time' -- as 'living is learning' - it happens automatically and spontaneously. I work part time from home and so can be flexible in how I spend my time. I suppose that if you have a full time job and can't stay with your son it's a different story. My son is 3,5 and while he is getting more independent, I'm spending most of my time with him. As he gets older I'm sure this will change.
