My son has begun shrieking and screaming, he’s almost 5mo! it’s absolutely adorable and doesn’t bother me one bit! But, is he finding his voice or trying to tell me something? Is it when he wants interaction or sleep 🤣🤦🏼‍♀️it seems sometimes it’s both. He used to babble and coo but now it’s all about yelling.

Totally normal?!
