My 7 month old is a "momma's boy" I can't be out of his sight and most of the time if I'm not within reaching distance of him he screams

This is my first child, so I don't know if this is normal for boys. I thought it was normal the first few months, but now it is starting to become a problem. He went with his dad one day so I could have a break and my husband had to bring him to me after 2 hours because he was screaming so hard and he wouldn't stop. Can anyone help me understand why, and what I can or should do to help him adjust to being with other people.
Re: 7 month old fussy momma's boy
As a SAHM, I'm the one around all day, so it makes sense that he has developed the attachment. I've just made sure to get out a lot, visit friends, family. I hand him over to others often. I wanted him to be happy and comfortable around them. And he is now, until he gets tired/hungry...then he only wants me. But I go think having interactions with others is key...and without you right there hovering.
I also noticed that I would stay very close to him all the time. If he was on his playmat, I was right there too. It got to the point we're he was so used to having me right there, that when I did get up to do something, he would fuss/cry. I started doing more things close, but not right beside him (in the kitchen were he could still see me), and now he's so much more mellow.
Hopefully it gets better for you! I know how hard it can be, especially when you just want a couple of hours "off".
7 months is prime time for separation anxiety. Babies only know what they are used to so suddenly being with someone new or even spending a day with just daddy can throw them off completely. Start small and get him used to others, have dad take him for smaller time periods like 30min, then an hour regularly. Ensuring they are fed and well rested helps a lot too.
Our daughter is 8months she's had periods where she can only be in my arms (they were short lived) now she is content with me or daddy. Random other people will set her off to an extreme but we never know who it will be to set her off. We make a point of being out often and passing her around as much as she will tolerate. She is usually content with a variety of people if daddy or I are in eye sight.
for the last month or so she will get very upset when I leave the room...if I talk and sing to her while I leave she will tolerate my absence. It's normal. I go about my day coming and going while she plays but there comes a point where she just needs me to pick her up and cuddle so sometimes things just don't get done.
A year from now you will be wishing he would let you hold him as he'll e constantly running away from you! It's hard in this phase but do your best to enjoy it while it lasts!
