Hi, My baby bot is now 2.5yrs old. From the beginning itself he used to turn purple when ever he cries for long. we thought he will be alright as he grew older and it was disappearing too. However, these days he is becoming purple as before as he cries for long, like when he is hard to reach me, or when he gets hurts him really hard he starts crying and he turns purple/blue like he is having difficulty in taking breath. Is it anything to worry about.
