Same here, my baby also likes to scream, she's 6 months and 1 week now. She's been doing that ever since she "discovered" she could make sounds. I believe it's normal (and diymummy is right) as once they discover a sound they can make, they will enjoy repeating it over and over again.I tried talking softly to her like , No baby , not the right way , shake head to her , she think i am playing with her so she smile widely to me and continue to scream till her cough & choke on her saliva .. Screaming and laughing away yesterday , nothing can stop her i tried to distract her by giving toys to her , she will take & scream alamak .. Hopefully she will be fine later , she started screaming since evening , activity time like this .. Am afraid she will hurt her throat or something
