One of my biggest parenting fears is raising a spoiled or undisciplined child. I know it's really hard once you have a LO of your own, but I really want to know how parents w/well-behaved kids do it?!
For example: What do you do when your baby/toddler cries and fusses in public and it's not for a "need" reason (diaper/hungry/etc.) I have one friend who always has to pick up her kid b/c LO is crying and fussing and give into whatever LO wants. Others say she is spoiling the LO by always giving in and whatnot. But then, I also understand why she does it. She doesn't want all the attention and looks from other people like "why can't she shush that baby?" Isn't she looked down on in both situations?

I know it's an age-old problem, but what is mom & dad to do when baby is crying or throwing a temper tantrum? Any advice or lessons from experience?

P.S. I've JUST started reading "Happiest Baby On The Block" from all the HB recommendations. Hoping to also unearth some secrets in there!
