My DS2 cried constantly until he was 6 months old.His elder brother hardly cried at all but has what I think is a form of autism , not diagnosed in those days (he is now 54)
DS2 is now a father and grandfather, holds down a steady job, and is well liked by all for his friendliness and easy going manner.
DS1 is exactly the opposite
Spider deterrent……. Not….🕷️🕷️🕷️🕷️🕷️🕷️
, DD2 was a shock. Even in the post-natal ward she’d be wheeled out of the night nursery because she was waking the other babies. Just as you describe above, unless I had her strapped to me (and even sometimes when I did) she cried constantly and rarely slept. No obvious medical problems. My district nurse asked me to keep a diary of her days and then told me a baby couldn’t possibly sleep so little and cry so much (helpful!). We never did get to the bottom of it, but at 6 months we suddenly turned a corner and from then on she was the most laidback, contented child anyone could wish for. Fingers crossed for you!
