If you are the parent of one of those easy kids who will drink formula at room temperature or cold, consider yourself lucky!
There is no magic temperature at which to serve formula, so it is really trial and error to see how your baby prefers it. Some mothers who are both breastfeeding and formula feeding serve the former right from the breast (warm) and the latter right from the fridge (cold) without any difficulty. For most babies, right around room temperature or slightly warmer is preferred.
