Both of mine had arsenic hour around 5 or 6 pm when they were young babies. No matter how much I breastfed them, they would still cry and cry while I was trying to make tea and eat my dinner. I often breastfed them on a feeding pillow on my lap while I was eating my tea! It was just the most stressful time of my life I think. It's something they do grow out of though. I think the turning point for us was when at 4 months I started them on solids and was able to spoon feed them while I was eating tea. I have heard that arsenic hour can drag on for hours, until 9pm, but I've never heard a solution. Infant's Friend helped my second baby with colic, but overall, I think they just have to grow out of it. Hang in there. It might not look like it now, but it will get easier. They are definitely grouchy around that time even as toddlers, but it's no where near as bad as when they are a screaming baby. Good luck. You're definitely not alone .
