But for your baby, who is just starting out on the journey of food discovery, introducing just one new ingredient every few days is the best approach.
Step One: Health professionals advise always starting the weaning process with a little plain baby rice that can be mixed with breastmilk or formula to form an easy-to-digest, runny porridge. Simple cereals like rice or barley are good, healthy sources of iron and B vitamins, and provide useful calories for your growing baby. Three or four baby-spoonfuls is sufficient at first, and choose a time in the day when your little one is alert, calm and happy. Don't attempt to wean your baby when he is screaming with hunger. Offer the food after he has had some milk but isn't completely full.
Step Two: Once your baby is happily taking his porridge, you can start thinking about offering bland vegetables. Steam or boil, then puree them, add some of the cooking liquid, and pass through a sieve to achieve a smooth consistency. You can add some breastmilk or formula, or mix in some baby rice to make the food more palatable. Bear in mind that babies are more inclined to acquire a taste for vegetables if you delay introducing sweet foods like tasty fruit. Once your little one is happily eating his greens, you can make things a bit more fun by starting to offer sweeter options!
Step Three: Remember to always give your baby a few days to get accustomed to each new ingredient, in case there is a delayed response. If he refuses certain foods simply because of the taste or consistency, don't discount them completely, but maybe try again another day, or add them to one of his favourite foods. This is also the perfect opportunity to use fruit and vegetables you don't usually cook for yourself. As long as you take things slow, you should try to be adventurous and introduce your child to as many different tastes as possible so that, in time, he will be able to have a healthy and varied diet.
