My baby has been on the same formula since NB. Couple weeks ago she was sick, upper respiratory virus. She had a lot of phlegm. She started throwing up a bit and I thought ok normal since she struggling to eat and had mucus. Last week she was still throwing up and I thought it was normal since she has been drooling and I thought it was teething. Saturday she vomited a lot like a puddle on my bed type of vomit. My mommy senses started tingling. Now today she vomited again and it came out her nose. She was struggling to get it out, now idk what is wrong I am worried. I have tried solids, but since she has been sick I given her like maybe once in the past three weeks. She is still on 4 oz formula and I have not changed at all. She poops once a day maybe twice, if I’m lucky. She doesn’t seam fussy or colicky. I will be calling my pediatrician to see her. Just thought I would share and see if anyone has been through this!
