Just curious if anyone else is going through this currently. My son turned 7 months on Sept. 14th and has just been extremely clingy. Like I can barely get anything done because he wants me to pick him up all the time. I'm a sahm so I'm always with him. I used to get an hour a day a couple times a week to go to the gym... but now he only lasts 10 minutes (literally) at the kids club before I'm called to get him because he's screaming!! Also he's been waking up crying 4-5 times a night and the cries seem like it's something hurting him and not so much a nightmare but idk really. And lastly, the whining! He used to be such a happy baby all day long and now he just whines about everything. He whines when he wakes up from a nap, when he's playing on the floor, while I'm feeding him... just about any situation he's in he whines!
