Hello ? I recently wrote about stains on diapers from urine, most likely because there's been less of it... thrush in the baby's mouth ? it hurts him badly since yesterday, can't eat normally.. seems like he's trying to latch onto his breast out of hunger, but then releases it as it hurts. I'm a mother.. I didn't notice in time ??‍♀️ Tomorrow we'll still submit urine, so here's my question: How do you collect urine from babies? Are there any life hacks? I bought diaper bags for boys, but how is that? To wear and hold until he doesn't want to pee? ?
