6 mo th old is suddenly never happy 😭😰

This mommy is losing her mind 😭😰

Every since he turned 6 month old on Friday (he had shots) he has not been happy at all. He’s happy maybe for 30imutes after waking then after that the rest of the day is miserable with him. I love him to death but he is really making day to day so hard . I hope it’s just a phase but in the mean time any one mind keeping my hair in a bag for me so I can reattach it when this is all over? I can’t be the only one who’s baby who has always been happy now a terror 😂
