Same happens to my 12 month old baby . Now that I have read the answers I Am relieved

It is normal . My baby even did. It's nerve development

If the doc said so then I don’t think you should worry dear

No fixed time. However, I also had a talk with doctor and he said shuddering is perfectly fine; this happens when young babies try to get accustomed to their nervous system.

hi vishwas - is this while passing urine or while sleeping or no fixed time?
