Ask Dr. JJ: Weaning My Baby Off Formula


My son is turning a year old next week and I would like to know how I can wean him onto whole milk? He is currently drinking 5 ounces of formula 4 times a day plus breakfast, lunch and dinner. Thank you.

Dr. JJ:

You can start by adding 1 ounce of milk to each of his bottles (while subtracting one ounce of formula from it.) The next day add 2 ounces, the next day 3, etc. Basically, over 5-7 days, you can wean him successfully. Watch for gas/constipation; if those occur, talk to your pediatrician about alternatives. Remember to give him plain water during the hot summer (avoid juices as a regular beverage) and limit his milk to 20-24 ounces over 24 hours so he has an appetite for real food!

    I am looking to do the same but I do not want to substitute formula for milk in a bottle. When he’s done with formula I would like him to be done with a bottle. How would one go about that? He has milk in a sippy but barely drinks any and he only has a sippy with milk at meals.
