do you know what womble? i feel the same. people constantly tell me they hope i have a girl.
sometimes i agree and sometimes the thought of not having another boy, a brother for my son, makes me feel sad too.
it's hard when you feel like it's always your dc being difficult. and it's bloody embarrassing!
be very consistent and firm, even if it feel like it's not working, it will eventually. took about 6 months of naughty step beofre ds got it. it didn't feel effective at the time but i didn't know what else to do.
things that help with my ds:
go for a walk every day;
change of scenary, sometimes playing in another room;
these are the rules:
he must hold my hand when walking or straight back in buggy,
throwing or hitting gets a warning and then on the step.
he goes to bed at a regular time, in his bed.
you'll be fine and imo you don't need to find out what you're having in order to get your head around it. you will be happy, whatever you have
