My baby has been crying relentlessly for the past 2 days due to constipation. She is taking Colic aid once a day ( 5drops) and also
Vitamin D3 and A to Z drops. She is currently feeding on Similac 1. This relentless cry increases especially in the evening. There is also a change in her poop colour. I have attached the picture. Please suggest a remedy. She is also spitting curdled milk. At present she is 6 weeks old.
