If your baby really doesn't like being on her tummy, leave it for now and try again another time. Bear in mind that babies develop differently, some more quickly than others. If your baby isn't rolling over by the time she is six months or seven months old, talk to your GP or health visitor.
Some men stop growing at 18, some at 21. Some men grow really quickly early on, and slowly grow taller until they have hit somewhere between 18 and 21, while others grow quickly later on and some just grow gradually. So, only time can tell you, no one else can because everyone is different.
Will vitamins help my son grow taller? Your son's height will depend on what stage he is in relation to puberty and on how tall you and his father are much more than his diet. Boys usually grow fastest during the last third of puberty and on average reach their mature height at about eighteen years of age. The first signs of puberty in a boy are usually growth of his genitals and sometimes growth of pubic hair. This occurs anywhere between 11 and 14 years. Fastest growth tends to occur a couple of years later, putting the average age for most rapid increase in height at about 14 Â½ years (ranging from 13 to 15 1/2 years).
