(4 pack) Similac Pro-Total Comfort Powder Baby Formula, 29.8-oz Value Can

We usually buy the non pro version of this formula, but because the price increased by $5 on similac total comfort now called similac gentle comfort, I decided to pay $2 more for the pro version. Long story short my daughter born preemie did not do well on similac sensitive it made her constipated. Alimentum caused her loose stool and the liquid form of it for some reason is better than the powder form. It's been a year on total comfort/gentle comfort and it works perfectly. She does have no form poop and it's green from this formula. The major issue but well worth it is that this formula and non pro version is very difficult to mix. So I make her formula in a mixing pitcher and use warm water. If you use room temp water and try to mix in a bottle you will be shaking forever to get the formula mixed and they tell you to twirl and not shake the bottle, but twirling will not get this formula to mix. Then if you pre make formula or bottles the formula will somewhat separate from the water and you'll see it at the bottom of the bottles or in my case the pitcher. To deal with that issue i just mix the formula in the pitcher again before making more bottles and shake the premade bottles before giving.
