Is my baby spoiled?

Quaya

FTM and honestly just realizing I may have spoiled my almost 5 month old?

She has me wrapped around her little fingers, I'm constantly entertaining her and when I do need to put her down she knows all she needs to do is start crying and I'll drop whatever I'm doing to comfort her. (I'm starting to let her cry a lil longer so I can finish dishes instead of doing a half load)

I was working part time short shifts (2-4 hours at a time) but ended up stopping because she would scream bloody murder basically the whole time I was gone and I just couldn't stand the thought and sound of my baby crying like that.

When I take her to visit my parents (or anyone else) she cries when they hold her (I take her every couple weeks) or even when I'm holding her and she looks their way! Its almost embarrassing that I may have created this monster.

My SO other kids come over every weekend and she loves spending time with them in their room, and my MIL comes over every other weekend and she's fine with her most of the time. I've noticed she acts so much different outside the house than she does in (normally a smiley happy playful baby until she leaves the house then she acts like she doesn't know how to crack a smile).

I guess I'm just looking for advice or your experiences. Maybe I can turn this around before she turns into a brat toddler. This post isn't an opportunity for mom-bashing! What works for you may not work for someone else so no need to tell someone how to parent, but ok to say what helped in your circumstance.
