It’s an exciting milestone when you can offer your baby solid food, introducing her to a world of tastes, flavors, and textures. Before you begin, it’s important to know what foods are safe to eat at each age. 

Babies can generally begin eating solids between four and six months of age. Remember, if your baby was born prematurely, you might need to adjust her age accordingly. Cucumbers are a great food choice once your baby is introduced to solids, as long as you prepare them according to her age and ability. 

You should only introduce your baby to one new food at a time to ensure she doesn’t have an allergic reaction. While cucumbers aren’t considered an allergen, it’s still a good practice to follow with the introduction of any new food. 

At first, you may mash or puree cucumbers, slowly introducing smaller chunks as she learns how to chew her food. If your baby is teething, peel a cucumber and offer it to her whole for teething relief with a cool, crisp taste. 

You may think cucumbers are a vegetable, but they are actually classified as fruit. They come in a variety of types that range from yellow to green in color. Smaller cucumbers are used for pickling, while larger cucumbers are used for slicing. 

Cucumbers are crunchy, cool, and mild in taste. One cup of cucumber slices with the peel has 15 calories and is a good source of vitamin K. Since cucumbers are 95% water, they are also a wonderful food to help promote hydration. 

When you first introduce cucumber to your baby, remove the tough outer skin and seeds. Not only does the skin pose a choking hazard, but it also leaves you susceptible to ingesting pesticides without proper cleaning. As cucumbers age, the seeds become bitter, so it is best to remove them before eating. 

Make sure you serve cucumber to your baby with age-appropriate preparation to avoid choking. Cucumbers are good for up to ten days stored in your refrigerator. Signs of spoilage include soft spots, sliminess, and mold.

Ideas for preparation include:

  • Mash or puree and feed with a spoon
  • Cut into small pieces to prevent choking
  • Grate the cucumber for a fun new texture
  • Slice into spears and roast in the oven
  • Spiralize as a noodle replacement

Before offering food, ask these questions:

  • Can my baby hold her head up independently? This is an important developmental milestone for eating solid food.
  • Is she interested in eating? Your baby may watch you eat with interest, even trying to grab your food and taste it. When you offer her a spoon, she should open her mouth to eat.
  • Can she move food to her throat? If you offer a spoon with food, your baby may push it out with her tongue first. This is called the tongue-thrust reflex. With time she will learn to use her tongue to push the food to the back of her mouth and swallow.
  • Is she big enough? Your baby should be double her birth weight and at least 13 pounds before beginning solid foods.

Offer a Variety

Once your baby begins eating solid foods, she needs variety in her diet. Once you introduce a new food to your baby, try to offer it to her again at least twice a week. When your baby is learning to eat, she watches you. Make sure you offer the same foods the rest of the family is eating for encouragement.

Consider Allergens

By the time your baby is twelve months old, she should be introduced to each of the common allergy foods:

  • Cooked egg
  • Creamy peanut butter
  • Cow’s milk (dairy)
  • Tree nuts (such as cashew or almond paste)
  • Soy
  • Sesame
  • Wheat
  • Fish and other seafood

By introducing these foods early in life, you can reduce your baby’s chance of developing food allergies. Only introduce one new food at a time when you can monitor your baby’s response to the food in case of an allergic reaction. If you suspect an allergic reaction, make notes about what happened and talk to your child’s pediatrician.
