Leukocytes are not limited to blood. They occur elsewhere in the body as well, most notably in the spleen, liver, and lymph glands. Most are produced in our bone marrow from the same kind of stem cells that produce red blood cells. Others are produced in the thymus gland, which is at the base of the neck.
Once your baby is past 3 months than that is no longer a newborn. But that isn't considered a toddler either yet. They are a baby up until they start to walk then they are called a toddler. Source(s): My opinion. chicken2008 Â· 6 years ago. Thumbs up. 0. Thumbs down. 0. Comment.
To adjust your baby's age, the number of weeks your baby is premature is subtracted from your baby's chronological age in weeks. For example, if your baby was 5 weeks premature (ie. born at week 35 based on full term of 40 weeks), and it's been 20 weeks since your baby was born, your baby's corrected age is 15 weeks old (20 - 5 = 15). Until recently, babies born between 37 weeks and 42 weeks were considered full-term, with 40 weeks from last menstrual period (LMP) being the average.
