2 year olds diet

My daughter will be 3 in November. She’s had issues with constipation basically since she started solids at 6 months old. Today I started writing down everything she eats in a day to either show her doctor or just figure out what I could be doing better 🤷🏻‍♀️ Here’s what she ate today. Opinions?

Breakfast-

3/4 of a peach

Oatmeal (with coconut milk)

1/4 a very ripe banana (very ripe shouldn’t be an issue and I only gave her a little)

Apple juice with probiotic mixed in

Lunch-

Fish sticks

Tomato

Raspberries

Whole wheat pasta with butter

Spinach with olive oil

Water

Multivitamin that also has 1 probiotic strain

Snack-

Coconut milk ice cream (dairy constipates her especially real ice cream)

Dinner-

Chicken sandwich with lettuce, tomato, a little cheese, mayo, on mostly whole wheat homemade bread

Extra tomatoes

Pickles

Cucumbers

Apricot/peach/apple juice

Water

I try to avoid the major constipating foods but I think that’s why she’s only in the 5th percentile for weight (although I probably am in the 5th percentile too as an adult so it also makes sense that she’d be on the small side) ?
