Too early you be SPOILED??!!??

A💓C • Married, 33 yrs old pregnant with our 3rd. I haves 2 boys ages (14/8) and praying for my little girl.
I believe my daughter who is 3 weeks old has colic?!  My doctor states to just console her when fussy, whining etc. She is like this at night only and let me tell you it's HARD.  When she cries an hr and half after eating I'll pick her up and rock her back to sleep then lay her back down. Sometimes she stays asleep and others she will wake back up.  My doctor says she is too little to get spoiled they just need the love. I'm afraid that she might be getting used to be carried to soothe and put her to sleep. What do you think?
