It's exhausting isn't it. DH and I have such different techniques. And at the moment, with him home helping after DD was born a couple of weeks ago, in some ways I'm finding it even more challenging! Sounds awful, but I'm more patient than DH, and him being here actually decreases my patience. I don't want him to go back to work, the help he gives is invaluable, but dealing with a tantrum throwing 2-y-o? Oh lordy, ready for that to stop. Apparently we have another 16 years or so (according to my Mum).
