Neighbor keeps calling police and DCFS

We moved in 6 months ago and we have a 2 year old. For months she’s harassed the landlord about our toddler waking her up at 8-9am, her running around, throwing tantrums. The landlord is a family friend so he tells us but just says she’s a child. She is now calling the cops and DCFS saying we’re abusing our child. She’s called 5 times now. The police just left my apartment about 30 minutes ago and I’m just tired of this. Every time they come, they hear no crying, no screaming. They walk in to a toddler playing with her dog or her toys. Laughing and she’ll even go and greet them! They see no bruises, no cuts, no issues and then they’re done but KEEP COMING BACK. Each time they come, I’m caught off guard so she’s just in a diaper and shirt so I mean, I’m not hiding I’m not able to go and put pants or anything on her and why would I? I have nothing to hide from them. All over my toddler waking her up and causing noise issues.. during the day. My daughter goes to sleep at 7-8pm every night so it’s not like she’s screaming through the night or anything. She even called one time and told them my boyfriend was beating on us and I had bruises all over my face. The cops came, laughed about the claim and left that time. DCFS has to have an open case because she’s called so many times so now I’m being harassed by them though, doing their job but each time they come, they take a picture of her and leave. No issues. I keep getting mail from them saying they’ve closed the cases and keep opening them up because of this. The most I can do is stomp every where I go, play music really loud. I’m planning on filing restraining orders or something when I can get the reports to me. She’s outted herself saying my boyfriend went to talk to her before claiming it’s because we were fighting but he went because she had the flu about a month ago and kept waking up, getting sick and then crying loudly, especially when we gave her medicine, so he apologized the next morning about it. She was the only one he spoke to about that as she’s under us. The thing is, she calls every other day. My child doesn’t throw tantrums every day. She calls on days when my child is quiet and doing nothing. I’ve never met the woman before, don’t even know what she looks like. Call DCFS on a family who needs it, not us. People who use DCFS to cause issues disgust me.
