Those habits are really ingrained at that point.
Absolutely! They are habits which are hard to break.
Right now, in my house, I have 5 daycare children sleeping for the afternoon. Every one of them went to sleep with no a peep out of them. Three of the kids fall asleep on their own at home. The little one - 1 year next week, gets rocked to sleep a lot of the time at home or co-sleeps with her parents. One of the 4 year olds gives his parents a hard time going to sleep every single night and usually ends up co-sleeping with them. Only after 10:30 at night do they finally get him to sleep -- every night.
What I'm trying to say is that because you've allowed Patrick (as some of the parents of the kids I care for have allowed their children) to learn these habits. If the habit is changed, so will the sleeping pattern.
As I said on the other thread, it won't be easy and will rip your heart out in the process. Children are very good a manipulating parents. As young as they are, they still know how to tug on our heart strings.
I will share with you the worst case of crying it out I've ever encountered. Last August, I started caring for a 7 month old who just wouldn't sleep. No matter what I tried, he wouldn't sleep. Mom rocked him at home. I even tried rocking him, but I wasn't Mom and he knew the difference. This little guy was so exhausted he would fall asleep in the stroller or in the swing if we were at a park. But, it was only out of share exhaustion.
Finally, I started letting him cry it out - Mom knew and was in agreement he needed to learn. At first, he would cry the entire nap time. I would go in, comfort him, and try and coax him to sleep. It took weeks before he would sleep even 10 minutes at my house. The little guy was very stubborn and determined he was not going to sleep. Then one day, instead of sleeping 10 minutes, he slept for 20. Gradually things changed. This little one just left for the summer (17 months old now) and just last week, all I needed to tell him was "it's night-night time" and he would walk right to his bed and wait for me to pick him up, give him his blanket and tell him "sweet dreams".
Habits can be broken. It might not be easy getting to the result, but in the end, you'll look back and wonder how you ever did anything different.
