Many of the suggestions in the comments make sense and will work for some children. Just keep in mind that every child is different and during some developmental phases things can shift and change significantly. Just because something worked for other parents, it may do the exact opposite for you. Sometimes being patient and waiting for a phase to pass is the only thing that works. It can take a week or two and in some extreme cases months or even a few years. Also keep in mind that trying something different every day will likely make things worse. Try something and (gently) stick with it for a while before evaluating.
Good luck!
Oooh, that explains so much. I had to switch the provider after many happy years with them and found a new home at Hetzner.
