:hugs:
My kids are annoying....god are they annoying but I don't think any of them pulled the mom mom mom mom type thing...maybe kid #4 (a 3 year old boy) does that a bit. But mine are usually to busy bickering with each other to bother me too much.
Maybe you could set up a little system type thing for her....make it a game or something....like make a "talking stick" or something and when she wants to talk to you she has to be holding that stick, maybe it will help make her aware of how often she is "pestering" or if her "mom mom moming" is cause the other sibling to not have a chance to talk....it might help the non talking one to maybe get a word in edgewise.
Or go to the craft store and buy some Popsicle sticks and give her like 15 to 20 a day and when she really really wants you attention she has to "give one up" or if she starts the "whining" you make her give it up. Then at the end of the day how ever many she has left she gets that many pennies, nickles, dimes whatevers ect. Maybe she will learn that the reward at the end of the day is much much sweeter then the whining all day long!!!
Nonetheless my friend...I feel for you!!!! Big giant :hugs: to you!!! Just remember summer will be ending before you know it!!!
