Should I let my kid eat the same thing every day?

Mostly yes, in the short term — but with one small move to protect yourself.

Kids get on "food jags" — wanting the exact same meal on repeat — and it's extremely common and usually harmless for a while. Forcing variety tends to backfire and add stress. The real risk isn't boredom or (usually) short-term nutrition; it's that a food eaten *identically* every single day can suddenly "burn out" and drop off the safe list for good — and losing a safe food is a much bigger problem than eating it a lot.

The protective trick: keep serving the food they love, but rotate its shape and format — the same nuggets as strips one day and coins the next, pasta plain then baked crispy. Small format changes keep the food feeling slightly fresh, which helps guard against burnout, without a fight. If a jag lasts many months, or the overall list is shrinking, mention it to your pediatrician.
