Did you become more bad tempered after becoming a parent?

I wouldn't say "bad-tempered", but I've definitely get annoyed a little faster. I feel it's just due to the sheer number of things on my plate as a mum and with work as well. It is most of the time due to me being tied for time for stressed and it's never my child's fault, really. So, understandably I feel pretty bad if I snap at my child. I've found that making sure I have time for myself to relax makes a huge difference. I go for a swim or do yoga to relax.
