Suitable Travel Times.
April, May, the beginning of June, the end of September and October are the best times to visit Turkey with a baby or toddler. The temperatures are more manageable at these times and it is less crowded. Summer (mid-June, July, August, through mid-September) is quite hot though usually rainless, and cool inland in the evenings. Seaside resorts are crowded and prices are at their peak, but the cities are less so. Skin can burn very easy in Turkey and coastal breezes can make it feel cooler than it is so be very careful if you are taking a baby or toddler there at the hottest time of year.

The month of August will see a lot of people fasting for Ramadan although you will be able to eat and drink during the day in the tourist areas. Immediately following Ramadan is the Eid-ul Fitr, a three-day national holiday where many offices and businesses close. Restaurants, bars and cafes will generally remain open during this time.
