Baby Poop

Would like to asked who ever have the same experienced as I'm facing now.. Baby now is 2M, currently since 10th Aug, he only poops once on 11th Aug.. Is it normal? Before this he will be pooping everyday once to twice per day.. His activity still normal such as 1. Feeding every 2 to 3 hours (EBM + FM) 2. Urinate a lot (change diaper frequent) 3. Tummy not bloated (xkembung) 4. Burping normal (especially when he is not comfortable) Should i be worried?? Anything that I need to take precaution...
