Is there a big psychological effect if sometimes you don't let your toddler "dede" from you?

If you’re still breastfeeding and your toddler sees you and you refuse, I’m sure there is as your kid is thinking why you won’t feed. Unless you are starting to wean. Best to talk to your toddler and make your kid understand and slowly transition to bottle. But if you’re away, I don’t think there’s a problem.
