Over the past few months DD has turned into a complete threenager (she turned 3yo last month). I've been trying so hard but I just feel like I loose my temper all the time and really struggle with her behaviour. I think it's just normal 3yo behaviour, she's just being a child but she's figured out that shouting and screaming really get to me. When she was a baby she had reflux and cried all the time. It was really hard and it was quite traumatising especially when we went into lockdown and had no one to give me or DH a break. The crying sometimes would last all day and all night too. I realise she was in pain and it was horrible for her but now that she is older and more cognitive (as much as a 3yo can be) I am finding her deliberate shouting and screaming very triggering. I hate that I feel angry towards her and it seems to me I have underlying feelings towards her still lingering from when she was a baby. How do I break the cycle and stop feeling like this? I fear its going to effect our relationship if I can't change how I feel towards her.
