I have been amazed, and thankfull!, at just how robust the most vulnerable little members of our family are.
Some things have been negligence due to no sleep or illness, some things have been due to it just not occuring to me that it would happen e.g I lock all the bleach away like fort knox only to find DD had decided to, and acted in the space I turned around to stuff her clothes in the laundry basket and find a towel in the same tiny room, take a huge swig of her dad's aftershave, it was more of a chug actually cuz I start 'em young - cue A&E fun. Some things are just outright unforseeable accidents.
I cannot count the hours I have spent feeling like hot coal pennance is not enough to assuage the guilt I felt at it happening. I learned, through the trial of more children - they do stupid shit, sometimes so do I, it's ok to be kind to yourself because you have learned.
And everyday I send a little nod to Mother Nature to say 'thanks for making kids able to survive new parents, tired parents, old parents and me'.
It's a whole load of responsibility it's true but try to take a step back sometimes if you can - a lot of pressure is heaped on parents, a lot of ideological thinking is pushed at you and it can become bound up with how you see yourself, what is essential etc; stop hammer time honestly, pare back the thinking. Your child needs food, warmth, comfort, love, safety. If, at the end of the day your child is fed, warm, loved, secure and happy it doesn't matter how you got there or any bumps along the way. When I stopped putting pressure on myself to be the perfect 'type x' parent I had a lot more head space to be the best IllageVidiot parent, a lot of anxiety left me - a lot of stress suddenly being removed meant I did less stupid shit...had the same amount of accidents but it happens. I'm not the perfect parent but I am perfect for my family - you will be too because you love your child and DH and will act in ther best interests - nobody said you had to do it as Gina Ford or Dr Spears, just as you, as best you can.
