TALK TO ME . So my son is 6 days old I noticed he’s having less wet diapers mainly just poop for the last 2 days . I took him to the doctors yesterday morning he peed there ! But they still wasn’t happy that he drastically slowed down with urine they told me if he doesn’t get a good wet diaper by last night take him to the ER. We ended up going they said lack of urine could mean dehydration they check his blood for it it came back normal he’s not dehydrated what so ever !! He’s breast fed he’s eating great every 2/3 hrs my milk has come in . In the hospital he lost quite a bit weight but he’s almost back to his birth weight within 2 days of us being home so they was happy about that . They said maybe his kidneys aren’t functioning well they did blood work for that his kidneys is functioning normal blood flow is normal . Since I was high risk they grabbed his images from my whole pregnancy and I had images done every single week in all pics his kidneys was fine which mean no blockage . He does not have a fever anything everything is saying he is absolutely fine !! So they discharged us and said follow up with his peds next week to check weight . They said it happens sometimes with slowing down of urine and because scans were normal and blood test of all sorts was normal they said not to be alarmed . But part of me is still freaking out because How can you drink all day and not have a good urine output at all times ? I’m not a doctor and like I stated they ran mad test and nothing said anything was wrong with him so I guess I shouldn’t worry but I can’t help not to 😔😩
