Well done both. 1,5 year here. Not addicted but wanted my now 1,5 year old to never have a dad to hungover to do stuff or have even the slightest change of personality because of drink.
Well done, you have one lucky child who will have a great life because of you. It won't be perfect, there are other factors in life but the fact you made that decision means they are better positioned than most.
When I started my recovery I met so many old timers with years of addiction and treatment specialist with years of experience who taught me that the biggest thing society should teach about addictions is that everyone should do their best to not even start. It's far easier to discourage someone from starting an addiction than it is to treat someone with 20 years of living with an addiction.
Keep up everything you do, your children will be happier for it. I'm happy for you.
