Similac® For Supplementation

For breastfeeding moms who choose to introduce formula

Similac For Supplementation is the first Similac formula designed for breastfeeding moms who choose to supplement. It has more prebiotics than any other Similac formula, along with the same benefits as Similac Advance. Some moms may notice changes in stool patterns when introducing formula to a breastfeeding routine, and studies have shown that prebiotics produce softer stools more like those of breastfed infants.

Feeding solutions

It takes time for a baby’s digestive system to mature, so a fussy baby
doesn’t have to mean switching formulas. 

Always talk to your pediatrician about feeding issues before making a switch.

Before switching, try these suggestions:

  • Use a different bottle or nipple.
  • Use a different burping position.
  • Adjust your body position.
  • Feed your baby less formula at each feeding while her digestive system grows.
  • Use liquid formula instead of powder.

Rated 5 out of 5 by Happy Baby & Happy Mom I am a first time mom and was determined to exclusively just breastfeed my son. However, that didn't work out good for the little one. 5 days after he was born, he loss 15% of his birth weight and was told by the pediatrician to start supplementing with formula. I was given samples of Similac & Enfamil. I started him with Similac & after a day of feeding him this product, he gained 6 oz weight and didn't have any digestive issues that I noticed/observed. When I ran out of the Similac samples, I gave him Enfamil supplement. It was a nightmare; I could tell right away that this product didn't agree with my son at all. He moves his bowel instantaneously after finishing Enfamil which gave diaper rash from the watery stool and I also noticed that he was gassy. Lessoned learned; I just feed him Similac.

Rated 5 out of 5 by In love with similac ! Since before my baby was born, I decided I was going to breastfeed 100% for at least 6months. One day my breast milk was completely gone and my baby was going crazy of hunger. I remembered I had received some "ready to feed samples" and broke my personal promise of never feeding him with formula. I WILL NEVER REGRET THAT DECISION! My baby accepted it completely fine and it made no changes on his feeding/pooping. After that day, I decided to purchase several packages of ready to feed and we use them as "snacks" between feedings whenever he is a little bit extra hungry. Then, I was told I had to undergo surgery and could not breast feed at all because of the anesthesia... I didn't think it twice and ran to the store and bought two powder cans and 3 packs of ready to feed bottles! (I got excited while at the store haha!) All I can think about is saying THANK YOU, because even if I broke my promise, I do not regret it at all! I have a happy fed baby every time I am unable to produce my milk all because of you!

Rated 5 out of 5 by This product is great! I used this product because i mainly breastfeed but wanted to give my baby a bottle while I'm at work. I really like this product because the first time i gave it to my baby his stool was like that of a breast feed baby. That really made me feel good. Then when my baby turned 2 months old, his pattern changed and was going every 2-3 days even up to 5 days! Then it changed to every other day. That was relieving. October 1, 2015
Rated 5 out of 5 by Supplement formula is what keeps us going! I was doing such a. Amazing job strickly breastfeeding but when I had to go under sugary my supply dropped dramatically and I had to supplement I joined the Similac program. But then my husband lost his job, we can't pay for our medical bills and can't get wic were stuck struggling to buy the formula ad Similac is the only kind my daughter can handle. But I would recommend this brand to any breastfeeding family. September 15, 2015

Rated 5 out of 5 by Awesome Nice supplement to breast milk. No spit up, doesn't cause gas, doesn't lump in water when mixing. Overall an awesome product. September 4, 2015
Rated 5 out of 5 by life saver! I had introduced formula to my son before and it broke my heart I didn't like what we used and t ended up making him very constipated. A few weeks to a month or so later a friend tried him on this formula at that point I felt like I can trust it and so I gave it a try because I was falling apart trying to keep up with his demand and all his heart break when he wasn't fully satisfied with how slow the flow of my milk went. This helped him get back on track and I feel safe and the best about using it it seemed a light was turned on inside my child he seems all around healthier and better. Thank you similac! :) September 3, 2015
