I'm sure it's just post Christmas stuff but both DC are really difficult to handle at the moment and I'm struggling with the noise aspect of it all. DD is 14 months and has pretty much clung to my leg, fed all night long and cried a LOT for about 3 months. she dropped her morning nap early at 9 month's and I'm pretty sure now she's walking she needs 2 naps again but she still relies on me to get to sleep but I don't have the time it takes to do it because DS needs me and will really play up if I'm not watching him like a hawk. he's nearly 3, wants my attention all the time, talks/sings/chatters literally all day long, asks the same questions over and over again whether he's had an answer or not, hums, recites rhymes and phrases and excerpts from books, he whines a lot and strops whenever he's told no. I've never given in to a tantrum, just ignore and then help him calm down when the angry part is over. DD is just crying this whingy cry all the time. I don't know if there's something wrong with me (auditory sensory problem perhaps) but the constant crying and whinging (especially when both are going at the same time) really affects me...I feel like I'm going crazy, get angry, want to throw things...I literally feel like my head is going to explode when there's so much noise going on. I get to the point I don't even want anyone to talk to me, I just want some peace. I crave quiet, my own personal space but any time I try and leave them even for a minute they become hysterical. 
I've been treated (hypnotherapy) for complex-PTSD this year, and also anxiety all due to a crappy childhood, but even so when I feel stressed I have no idea what to do..it overwhelms me. on the whole I'm trying to be a calm and patient Mum but the past few days have been so stressful it's escaped me somewhat. I meditate most evenings but am finding it hard to fit in in between chores and DDs frequent feeds. DH is great and does his share and more when he's here but works a lot, also because the DC are used to me they'll only be comforted by me. if they hurt themselves or are upset and he's holding them they'll almost throw themselves out of his arms to come to me.
I love my DC so much, they're both amazing and we'd really like more children, but I need to know why noise affects me so much and what I can do about it. I've been concerned that DS may have some kind of sensory disorder but now I'm wondering if some of it is me projecting - I was expected to be quiet my whole childhood so I wonder if my extreme reaction to prolonged crying/whining is down to this, normal anxiety as a parent or something else. any thoughts?
