Hello Sarah!
In this scenario, at one month corrected age the child score in the low average range on the TIMP. Since the infant is not showing any major delays, supporting the family with a home program on areas that the child might be needing more help in would be best in this scenario. In the clinic, if there are any other more concerning signs (ex. asymmetries, abnormal GMA score, etc.), more frequent therapy would definitely warrant increased frequency and a more urgent need for therapy. In this case, no other signs/symptoms were noted in the question, so HEP with scheduled follow-up would be the best plan.
In the case of the TIMP, it is still a good measure to determine if delays are present at any age. It is just most predictive of future motor delays at approximately 3 months corrected age.
