Wonder if anyone might have some ideas.
My DS is just over 4 weeks old and the last 3-4 days has been very unsettled at night, often after 8pm. He can go from being calm and peaceful to crying uncontrollably in a very short time with little build-up. The cry is very piercing. It usually happens a short while after his evening feed (formula-fed) so don’t think it’s hunger and it doesn’t seem like wind or colic either though could be wrong, when we try to wind him he resists. He becomes very awake which I know is common at this age as day/ nights still mixed up and it takes a long time to calm him down and pacify him, often up to midnight. We give him a soother which he sucks frantically on but don’t want to make this a regular habit. Wasn’t sure if the lighting makes a difference, if he gets scared of the shadows or the darkness as we dim the lights. Grateful for any advice
