We tried a few similac products before this one and none agreed with her and supplementing with breastmilk. She was constantly fussy and gassy. Also from birth she had very slow weight gain. We started this formula and within a month she gained 4lbs. She now has a little fat on her bones and we are grateful for how well she does digesting this formula.

It used to be that you had to get Kendamil formula or order from Europe in order to get good quality formula, but not anymore. The ingredients in By Heart are fantastic! Would like to be zero seed oils, but it's better than anything else on the American market. My son loves it and has no gut issues from it. It's a great compliment to starting solids.

We started with another formula for my son around a month old. He was not liking it, he had tummy troubles and gas. Once we switched to by heart he's been able to sleep comfortable feel fuller longer and be the content happy baby were used too. While we don't exclusively use formula Byheart is a great addition to the breast milk we use.

We found ByHeart while my baby was struggling starting at 6 months to get enough breast milk from me. We were exclusively nursing and all of a sudden she would wake every 1. 5 hours through the night, to nurse. In my own exhausted delusional state, I thought it was due to every other reason on the book - jet lag (we were traveling), teething, needing comfort) not once did I think hunger. Every 1. 5 hour wakeups continued for two and a half months. Until I decided to give some bottles with formula before bed. After a few weeks of looking for formula I felt good about giving, we landed on this stuff. Thanks to getting more to eat, she only wakes up once a night. I truly never thought possible! I rest easy knowing that the ingredients are top quality, that it’s organic, and the container, delivery system is incredibly user friendly. Oh! It’s dissolvable and the subscription service is icing on the cake. Now she’s fully transitioned to this formula. I’m grateful.

When it became apparent we needed to use formula for our baby, we were nervous about the long process of finding a formula she would tolerate well and take. We'll, we tried ByHeart first and it went swimmingly! Our baby loves it and we've had minimal to no digestive issues (either dishes or constipation), and almost no spit ups. I also love that the company controls their supply chain and tests for sooo many contaminants. The only (very small) issue is that it's quite foamy. If we prepare it right before we give to our daughter, we pour off the foam. But it's really no bother.

I do not produce enough milk to fully feed my baby, so I researched formulas and decided to try Byheart. My baby has no problems switching between this and my milk. I appreciated their approach to making this formula and find my baby has no gas problems, has regular and normal bowel movements, and seems to enjoying eating it. There was recently a consumer report that indicated that this formula has near the daily limit of lead, which is why I have only given it four stars.

We weren't expecting to use formula, but life had its own plans. We tried to choose carefully before we picked a formula and By Heart was our first choice. It worked so well for our baby and our family that it quickly became our only choice. If we need formula again next time we would choose By Heart again every time.

We began formula as a supplement, but now are exclusively formula feeding. The formula we started with seemed to be giving her gassy belly aches, and spitting up was becoming more often. The switch to ByHeart was the best thing we could've done. No more belly aches. Spitting up has become almost obsolete. It dissolves better. And I feel much more confident and at ease about the ingredients being put in her tiny body. While a little more pricy, I will gladly pay more for better quality.

Our baby has been bottle fed on only byheart. She is happy and healthy. Sleeps very well, is barely ever gassy, and is growing like a weed. 20 lbs at 6 months. I love the quality of the cans and the strict testing byheart goes through. Living in America where everything is filled with junk, byheart is the best option for anyone's budget. Also take advantage of the sales and bulk buy for a few months. They are definitely worth it.

I was pleased with this formula and my baby prefers it to Enfamil, but I was disappointed that the Consumer Reports study found lead in it. Ultimately I felt uncomfortable continuing to use it and switched to another “modeled after breast milk” formula that showed no traces of lead.
