So far I’m only on day 4, so I hope to see additional improvement, but my baby was crying for 5-6 hours every night. Since starting Evivo, that has gone down, but he still has issues around 1am until about 4am. The first two nights it seemed like he was maybe feeling worse, although he would and still does fall asleep almost immediately after his nightly dose. I considered discontinuing use but remembered that upon taking probiotics myself, sometimes you can feel worse for a bit. The 3rd and 4th nights have been better. My biggest complaint would be that it smells like tuna, but my son doesn’t seem to be bothered by the taste.
