DS is 5 and a half weeks old and has been suffering with wind and/or reflux for a few weeks and has a bit of a meltdown most evenings but will settle eventually and then go for stretchesof up to 5 hours. Today he woke at about 8 and has only slept for approx 1.5.hrs in half hour bursts and then wakes in visible discomfort. He's cried and cried and pretty incosolable. Is feeding ok and trying to keep upright and wind for at least 30 mins. His fontanelle is slightly sunken but have had wet and dirty nappies. Is this just a particularly shitty colicky day or could there be more to it? Tried gripe water to no avail just given some infacol, which didn't do a lot in the past as it seemed more of a reflux issue before. Feel at the end of my tether.
