Toddler aged 1.5 years old Often writes frequently I hold her diaper free during the day And she pees every half hour She drinks about 4 cups of tea per day Feet warm (not cold when touched) Has anyone experienced this? My first child has never had any experience with it, I'm worried Is it because she drinks too much or could it be that she is getting frostbite or something else? Does anyone know or have experienced this?
