Baby is now 4 months and wakes every 30mins to 1 hour. He has to be fed to sleep again as nothing else works. I’ve tried a dummy he spits it out. Also, he has cradle cap and he keeps scratching his head vigorously. I believe this is contributing to him waking up multiple times a night. I also find he is now difficult to put down. I could put him down in his cot before, but over the padt week he only had wants to sleep on me foe naps and will sleep next to me at night.
