In medicine, the BUN-to-creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL). Outside the United States, particularly in Canada and Europe, the truncated term urea is used (though it is still the same blood chemical) and the units are different (mmol/L).
Your child must be both physically and emotionally ready for toilet training. Most children are ready to start when they are between 22 and 30 months of age, but every child is different. Toilet training usually becomes a long and frustrating process if you try to start it before your child is ready.
Steer clear of worrying about hard and fast deadlines. No matter what your mother told you, thereâs no one right age to start potty training. Most children show signs of readiness sometime between the ages of 18 and 24 months. Once you do get started, potty training takes about eight months, on average. With a positive outlook and a little creativity, potty training really can be more about quality time. Find ways to encourage your childâs early interest.
