In the first four months, your baby will continue growing at the same rate as in his first few weeks of life, gaining an average of between 700g and 900g, and growing 2.5cm to 4cm a month.
Get ready for a growth spurt — most babies double their birth weight and grow 30 per cent in length by their fifth month.
Birth weights matter less than you might think — a small-sized baby might grow into a strapping adult, while a large baby can slim down in time to come. You and your husband are the best indicator of your baby’s future size. Are you tall, short, slender or heavy? Chances are, your child will be similarly built as an adult.
Babies’ hair growth patterns can vary widely. What’s more, your little one may lose all the hair he was born with during his first six months. Don’t fret — although it may take time, his hair will grow normally at some point.
If junior has started crawling and cruising, his muscles will develop as he starts to use his arms and legs more actively. Because his bones grow rapidly, too, his body and limbs will stretch out, making him appear leaner and taller.
Your doctor will check that your baby is gaining an appropriate amount of weight (no big dips), as well as make sure that he isn’t piling on an excessive amount of weight for his height, which might indicate potential weight problems down he road.
Your baby’s first tooth appears at around six months. When he’s teething, he might become fussy and lose his appetite. Don’t worry, he’ll regain his appetite once those pearly whites have erupted.
Don’t be too concerned about percentile ratings on the height and weight chart — if both parents are shorter than average, it’s perfectly normal for a healthy child to be in the lower percentile for height.
By your mini-me’s first birthday, he’d probably have tripled his birthweight and grown more than 50 per cent in length.
His physical growth has slowed down considerably by this time, however. In fact, he would probably gain just 2kg to 3kg in the second year.
He will still show a baby’s typical characteristics — a large, round face, short, pudgy arms and legs, as well as that trademark potbelly.
Once he starts toddling, his baby fat will disappear slowly, his arms and legs will lengthen, his face becomes more angular and you’ll begin to see a more defined jawline.
