Wow, I really dont know what I would do in your situation!! I see your dd has some special needs, and that accounts for alot of her destruction. I agree with the other posters about just getting rid of as much stuff as possible. I imagine it must be so hard with a 6 yo and a baby with special needs, especially as a single mama. Kudos to you just for surviving!! And for wanting to better your situation. I have tried those magnet locks, and they work fantastic. They are inside the cabinet, so you dont see them from the outside. They do require some tools and instalation, so I dont know if you know how to work a power drill, but be aware that they do require some know-how. (DH had to put these in for me) I would also, as you are de-cluttering, keep your 6 yo with you at all times. I know this sounds next to impossible, but it would be necessary only for a short time. When you change baby, have her help you, or sit down next to you. When you feed baby, have her sit next to you and read a book. Take a shower together. Take her when you go potty. I think sometimes (and I dont know much about SID, so this may not apply to your dd at all) kids get into a pattern, and they just need to 'forget' that pattern. For instance, she is probably doing this for attention, or out of boredom, when you are busy doing other things. If you can consistently (like say for 2-3 weeks) give her other options of things to do when she feels this way, she will probably change her behavior. I hate to use the term 'conditioning' but yeah, kinda like that. I hope this helps, and I hope you are able to get some help as well! Good luck to you.
