The 4 Day Wait Rule is a simple way to check if your baby has any reaction from the new foods introduced in the form of food allergies. Along with the possible allergic reactions, foods may cause tummy problems such as pains, gas or even poop troubles. You must introduce new foods at one time with the gap of days.

For instance, introduce baby to avocado on the first day and then wait for the next 4 days for any reaction before introducing the next food. When you introduce new food to your baby, it takes a few days to determine how exactly that particular food is reacting to the baby. It is very crucial especially in the initial days to keep track of the 4 day wait. This is also important if your family has a history of food allergies.

With the recent studies and research, the 4 day wait rule is going obsolete though. Many pediatricians suggest that one should introduce its little one to a variety of food all at once. The reason to offer a variety of food at once is to train the baby’s taste buds. Make sure that you do not forget to add herbs and spices while introducing new food because the earlier the better. 

4 Day Wait rule is emphasized if your family has a history of food allergies. Reactions may be in a form of digestive issues like diarrhea or constipation. 

Make sure that you always give new foods during the daytime. This will help you deal with the adverse reactions and you can also consult your pediatrician during their working hours. 

Once you introduce new food to your little one, you can mix it with different recipes and try out new ingredients for variety. You may start giving new foods to your little one when he is around 9-10 months old. As you loosen up with the 4 day wait rule, make sure that you still pay close attention to the different varieties which are offered to the baby. If the allergies or reactions continue, do not hesitate to consult your pediatrician.
