<human>: Summarize the given text in a few sentences.

My SO & i have a son who is about to turn 1 on July 21st. He's honestly a very happy baby. However, when he doesn't get his way, he bites you if your holding him (he currently has 7 teeth) , throws his body & head back on the floor, & will not stop throwing his tantrum/crying until he gets his way. He's a very smart baby, but that can sometimes be a little troublesome sometimes.

The reason he is this way is because we used to let my grandparents (our son's great-grandparents) watch him while we had to work since he was 4 months old. (We were both working full-time to support our family).They would pick him up at any sound he made & give him any toy/snack he wanted. so now our son expects to get what he wants, when he wants.we tried several times to ask them to ease him into being able to do things on his own. We are in the WIC program & were involved in a program that sent a home - visit nurse to make sure both myself & our son were on the right track.both the nurse & WIC counselor agreed on our concerns. So I had a very kind talk with my grandparents about how they were treating our son. They took it as disrespectful & that since they watched him in their house that they were going to raise him how they wanted. The last straw was when they threatened to call CPS on us simply because we had just gotten home from visiting my SO ' S father & it was a little late. It was about an hour past our son's bedtime & he had fallen asleep in his carseat. Now they are no longer allowed around our son until they can respect our parental boundaries & we are trying to fix the damage they caused.
<bot>: My grandparents babysat my son for 7 months while myself & my SO we're at work, they spoiled him because they didn't respect our wishes for our son & now we're trying to figure out how to unspoil him.
