If your breastfeeding toddler is eating a variety of solid foods, her nutritional needs from your breast milk are really quite small. (Meaning solids can fill her with the calories she needs for hitting the playground and having hissy fits.) Breast milk still provides some great perks though. Research shows that the antibody levels are highly concentrated as your milk supply decreases during weaning. So the milk your child gets — even if it's not a lot — can seriously help protect her from illness. (And that's a big plus, especially if she's hanging out with other kids on the playground.)
Do, however, try to maintain a healthy, balanced diet. This will give you more energy for motherhood and provide a great example for your little one to follow.
