Can I extend my Non-O visa for a Thai child for 60 days instead of the 1-year extension in Chon Buri?

The user is inquiring about the possibility of extending a Non-O visa for a Thai child by 60 days, as immigration in Chon Buri is insisting that the only extension available is for one year. Responses indicate that the 60-day extension is typically available under the 'visiting family member' reason and may not apply to 'half Thai child' cases. A successful extension was reported in Phuket Town, suggesting potential differences between immigration offices.
