I have one ds, and all the usual disclaimers, he's gorgeous and bright and affectionate etc and doing really well. Doesn't whinge much, has occasional short lived tantrums so I certainly don't think he's any worse than any toddlers but don't know if my reaction is normal!
The sheer intensity of parenthood is Absolutely overwhelming for me, the fact that you are never off duty and dealing with general toddler irritations (running off at bathtime, not wanting to get dressed etc) all trivial in themselves but sometimes I just feel so cross 
which makes me sad. I don't want to be shouty mummy. But it's just so frustrating! Do other people feel like this too?!
