I am in no way a pediatric psychologist, so this is just a laypersons' advice. All of us do have our compulsions, but most of the time they aren't particularly maladaptive - in other words, we can still live a healthy, well balanced life. When obsessions or compulsions start impeding our abilities to do other things, then they become maladaptive and problematic. If your daughters compulsions are just a little annoying to you because it takes you forever in the grocery store, then it's probably just a phase and it will pass. If she really gets upset if things are out of place, pitches a fit in the grocery store, won't get out of the car because of where it's parked, etc, I would talk to the pediatrician. If you are pretty confident that her compulsions are more than normal, I would be prepared with specific examples, and really push for a referral to a pediatric psychologist. Hopefully everything is developmentally appropriate, but if not, it would be so much better to have it addressed now than for her to suffer (because if these compulsions are really worse than normal, then it is suffering, even if she can't explain that.) And by the way, there is a ton of evidence that OCD is biologically based, so don't beat yourself up over this. Good luck.
