So LO had been struggling a little bit yesterday to poop, she finally got it out and it was almost the consistency of peanut butter and that was about 12:30 yesterday afternoon. Fast forward to just now and she finally had another poop but it was a small firm ball - I know this is a sign of constipation. I'm just freaking out as my pedi office isn't open yet and I'm not sure if this is an emergency or not. Background, we had been doing ready to feed formula and about 1 bottle of breastmilk a day, sunday we switched over to powder and my breastmilk supply has been dwindling. Is this an adjustment period to the powder and lack of breast milk or is there some other issue that could be present. Has this happened to anyone else and what happened. Thanks, just hate seeing my little girl uncomfortable

ETA: we use Similac Soy Isomil, she's 5 1/2 weeks old, and plenty of wet diapers
Re: Baby Poop Help!
We used formula with DS1 and his stools changed a lot while we figured out what to use.
Is there a particular reason you're using a soy formula?
