What should we expect at Immigration concerning our toddlers' overstay on Ed-visa and returning to Thailand after a week?

The user seeks advice regarding their situation of having two toddlers who have overstayed their Ed-visas for one year. They plan to exit Thailand for a week to Malaysia and are concerned about potential issues upon returning, especially regarding the immigration process given the overstay. Responses indicate that toddlers generally do not face fines or bans for overstays, but there could be questions about the legitimacy of their Ed-visa, and extra care is advised to avoid complications during re-entry.
