Is It Just Me?

Today Rachel had speech therapy.  She gets speech in school, three days a week, and I take her in to someone else once a week.  Rachel has had speech since she was an infant.  Over all these years, I have been given numerous oral motor exercises to do with her.  I always try to be the good mommy and attempt to do what I am told, but it never fails that, even if I get off to a good start, I end up tappering off.  I always have some excuse not to do them.......it is too late, Rachel is too grouchy, there is not enough time, I will do it later, Rachel doesn't feel good, I don't feel good, we are off our schedule with travel or friends visiting, etc.....  I always have good intentions and have spent lots of money on these intentions, only to let them fall by the wayside over time.  Take the eProReading program.  We got through the first coouple of sets of cards, and then I started missing days.  Days became weeks, and now we are not doing it at all.  Am I the only one out there that has a difficult time doing all the recommended exercises? (I am not any better with the PT or OT exercises either, by the way)  If you are good about following through on things, how do you do it?!  I just feel overwhelmed with the things I am supposed to do.  All three girls seem to have a thousand things that they are supposed to be doing, and I feel like I just cannot keep up.
