Hi, firstly don't ever be afraid to tell your hv, midwife and doctor anything, they certainly won't think you're a bad mum at all. Some babies do cry all the time and if could be for a number of reasons and if you discuss these with your doctor they can help find out what it is. It could be something as common as colic, I note you've tried a few things but they don't always work and it is something baby just has to grow out of, could take days, weeks or even months every baby is different. With reflux there are two types, silent and just normal reflux. Silent reflux is obviously hard to diagnose as there are few signs but baby will be in pain after eating, a bit like heart burn. Vomiting is a sign of reflux and straining or stomach crunching, my lo had it but not for long but it later turned out my lo had an intolerance to lactose, I changed his milk and he was back his normal happy self over night. Discuss all possibilities with your gp, it might take a few attempts to work out the problem if there is one but you need to talk to your hv midwife, doctor etc, they are there to help you. Be warned though, some doctors are reluctant to do much some times so be persistent! Another thing I found with my lo as well was he often had trapped wind, ensure you're winding a lot to make sure the wind is coming up. We switched our bottles to mam colic relief bottles, not everyone thinks the work but they did for us, they help reduce the amount of air baby drinks in. Infacol also worked for us to help get wind up. It might be that you just have a baby that cries but you will soon work out how to help them stop, four weeks is still very new so don't worry, it's all very normal. Good luck x
