Preemie Baby growth

Preemie baby growth and development
Preemie babies may later develop problems both for developmental difficulties, physically problems and mental problems tend to appear gradually over the first several years of life. These developmental problems include major handicapping conditions, such as cerebral palsy, mental retardation, blindness and deafness, but also include more common issues like developmental delays, growth problems, and various types of sensory impairment (vision and hearing problems). Early identification of developmental difficulties is believed to be critical to the success of treatments for these conditions.
Many parents of preemie infants have concerns about their child's growth - before and after discharge from the NICU.  For some families, these concerns can linger well into childhood and can lead to worries of permanent stunting of growth.
the growing preemie baby
Micro preemie babies are tinier at birth and tend to be sicker.  Sicker preemie babies are harder to nourish properly at first.  They may not tolerate the IV (intravenous) nutrition and may be harder to feed.  They lose weight early on (much of this is water weight, but some is actual body mass).preemie babies have special nutritional needs because they grow at a faster rate than full-term babies and their digestive systems are immature. Neonatologists measure their weight in grams, not pounds and ounces. Full-term babies usually weigh more than 2,500 grams (about 5 pounds, 8 ounces), where as preemie babies weigh anywhere from about 500 to 2,500 grams.  Finally by the time they are two to three weeks old, they have regained their birth weight, but may grow quite slowly for some time. 
85% of premature infants have catch-up growth and land on the regular growth chart by two years of age.

Do not worry about your friends baby born full term sitting up at 9 months and your preemie baby born premature on the same day only just supporting his or her head up. Preemie babies will catch up in all areas of learning including speech by the age 3 your health visitor will pick up on any difficulties as she asks you ongoing screening questions to make sure baby is on track.Referrals can then be made such as speech therapy,further hearing tests, therapists etc as and when the need arises.
