Super clingy baby

ai yo...baby ze is super clingy recently. He cannot be left alone for even 1min. The moment I put him on the floor and step away he will cry till his face turn red.

hmm...could he be teething? I don't know. There is no white spots on his gums, neither is there sharp edges. With the HFMD on the rise, have to be doubly careful.

It could also be Separation anxiety
At this age, most babies have typically already begun to show the signs of separation anxiety. Your baby may start to be shy or anxious around strangers, especially when tired or irritable, and when you're out of sight and not with him, he'll become upset. Although it's hard to see your baby distressed, it's important to let him experience this. When you leave your baby and return, proving that you always come back, you're helping him develop trust and the ability to form attachments to other people
