Whingey baby

Ever since my baby turned 14 weeks it’s just whinge whinge all the time. There’s nothing wrong with her like hunger nappy whatever but 1-8 weeks just crying constantly, 8-14 weeks totally new baby so happy all the time and smiling then 14 weeks hit and back to the constant crying and moaning. It’s exhausting seriously i understand that’s her personality clearly but omg some days 😩 and esp looking forward to the first Xmas as a family but the way things been lately I know she’s going to put me in a bad mood. Before anyone says about wonder weeks I know because they’re like clockwork with her but leap 4 is apparently 1-42 days?! So basically she’ll be like that for 6 weeks? Send help 😵‍💫😂
