'All the time' is only a very slight exaggeration, we have hours of crying/nagging/whining for things every day, it is driving us all mad. Really hard to have fun as a family when whatever you do one DC is miserable the whole time.
If she trips and gets the tiniest scratch her knee she will wail for hours, and then limp around for a few days. I find it so hard to be patient with the endless whinging 'my leg hurts', 'I'm tired', 'I'm hungry', 'I'm thirsty' (I should add these last too are often right after a meal/snack & drink, I promise I'm not depriving her of food and drink!) It's often really hard to get anything done at home because she'll cling to my leg every five minutes saying, in whiney tones, 'I need a drink/cuddle/snack etc' when I'm trying to cook dinner for example.
I know it sounds very old-school and the sort of thing I never thought I'd find myself saying but I'm desperate for her to toughen up a bit. I feel like I've tried everything, have tried being loving and giving her endless cuddles, I've tried getting tough and saying I want her to stay in her room/sit on the stair until she's finished moaning, I've got cross with her on countless occasions (not proud of doing but I after a whole day of it my patience just runs out).
I'm really at my wits end. DD2 is just so much easier to be around at the moment and I'm worried that DD1 will pick up on how I feel about it and that will make her feel resentful/make the situation worth etc.
Please, please tell me that your DC have been through this and that either you did something that successfully stopped it or they grew out of it (preferably by the age of four!).
