Hi Tamara,
My daughter is two and I am a stay at home mom who also works part time. She is very used to getting my attention. I can say that when my husband works from home, we have similar issues sometimes with her like the ones you mentioned. She tends to act out a bit when she is not getting her needs met. For her that is if she is hungry, thirsty or wants my attention.
I am not sure if this is what is going on with your child, but you could try scheduling time and attention for her. You may already do this, but if not then it would be very beneficial for you and your daughter. The way that I stop the struggle is by including her in whatever I am attempting to do. An example is, today I cleaned the closet, and she handed me hangers. Sometimes when I do dishes, she can put in cups and spoons, and plastic items. It makes her happy because she is included and me happy because she is learning how to do these tasks.
Another thing you could consider is her diet. Is she eating good nutritional foods? I had to adjust hers a bit recently and she is much happier most days. She would have sugar and act the way you described. We now limit her sugar intake a lot. You can always get her food allergy tested if you like? We have been planning to do that, but have not gotten aroun d to it.
Oh, and with Potty Training there is a great DVD called Potty Power I reccommend. My daughter loves it! She asks for it by name! It is very creative because it has a real toilet and discusses all the steps to pottying. There is also a site called pottytrainer.com which was helpful. It has a book you can purchase online to assist with how to do potty time.
With our daughter we involve her not only in playdates with other kids, but her own activities as well. She does swimming, music, and gymboree class. The last class is on Saturdays and can involve dad. Some times I use it as a break for my "me" time. We are also considering toddler Karate in the future. It can be done when you work from home, but is more challenging. My daufghter is very active and independent because we began this routine very early on. :)
One final thought is her teeth. Is she getting her 2 year molars? Teething can cause all kinds of crankiness. Best advice, breathe and consider what you say and how you are going to say it before you do. I have had moments where I just take some time when the crankiness hits so I do not get frustrated. When I get frustrated she gets frustrated too. If I stay happy and upbeat my daughters temperment is that way as well. It sounds like you are doing your best to stay patient and find solutions to the issue. That means you are a devoted and loving mom and she is blessed to have you. :)
Blessings,
Katherine
