It is highly unadvisable to give a 2 month old cow's milk. It is very hard for them to digest. As you say it is to be for a short time---have you considered pumping your breast milk and saving the extra. Use the saved milk while you are away from your baby (or whatever the reason you are needing to stop breastfeeding temporarily) and then you can resume breastfeeding when you are back. It is by far the best solution.
I switched one of my children to cow's milk at 13 months old and they got terribly sick. I was changing diapers continuously for weeks if you know what I mean.
