Baby sleep set Yataş?

'Baby sleep set Yataş' is not a general product name; it's Yataş brand's name for baby bedding sets (sheets, pillows, blankets). As a brand, Yataş generally has good quality standards, but when choosing the right set for baby, independent of brand, I recommend looking at these criteria:

• Breathability: Cotton fabric (at least 100% cotton, preferably organic) prevents baby from sweating.
• Fire safety / flame retardant chemicals: Make sure baby blankets and pillows don't contain flame retardant chemicals (these can contact skin).
• Blanket thickness: Sleep sacks are recommended instead of blankets for babies under 1 year; if there is a blanket, it should be thin, unfilled, with tight weave.
• Pillow: Pillows are not recommended for babies under 2 years old (sudden infant death risk). If the Yataş set has a pillow, set it aside and use only sheets and a light cover.

Check the Yataş product: Does it have an 'Oeko-Tex Standard 100' certification (which shows it contains no harmful substances)? Does it list an age range suitable for babies? If these aren't clear, it may be safer to look at alternatives.

The mattress itself is also a separate matter—if the bed is also Yataş, the mattress firmness (shouldn't be too soft, should be an orthopedic baby mattress) and ventilation are important.
