Given the task definition, example input & output, solve the new input case.
In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good.
Example: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Output: 5
The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

New input case for you: Others may have a different experience. We were using this as a supplement to mother's milk because mother's milk just did not seem to provide enough fat / protein for baby to gain weight. Problem, although stated that Goat's milk is easier to digest, we found that once we mixed the goat milk with mother's milk, she ate more infrequently and got constipated with indegestion. We had bought this to help with digestion, as Formula is based on cow's milk. This goat's milk seemed to have the opposite effect on our baby, and she didn't gain weight. Also, the taste isn't so great. We can use it as back up, in case we don't have milk in the fridge. So, it's OK, but I probably won't buy again.
