I'm not giving hate, I promise. But, . . . as a mama myself, I wonder if there might not be a better solution to your anxiety and depression than being high. I understand medicinal purposes but it does still have a chain reaction of making you high as well. And I know, I need to be completely clear headed and not buzzed when with my kids.
So, does TCH pass into breast milk? Well, it's an issue of full testing on this because no one will use their own kids as guinea pigs. And doctors would never run a study that *could* jeopardize an infant. Same with all things, medications as well. There are often not a lot of studies done on infants and young children for the safety of the kids. They have, however, tested it on monkeys and it did pass through the milk to the breast fed baby.
There are traditional ways to treat anxiety and depression and not always medication involved. Therapy is really great, CBT, to help learn to face issues and have appropriate coping skills. Self soothing techniques help. Exercise is a mood stabilizer. Meditation, hypnosis, etc. When medication is also used that is traditional medication, it doesn't have the residual affect of being high. I don't judge. It's not about that. It's just a more complicated lifestyle. And as your kids get older and others smell it on you or your kids for being around you, it gets trickier. But your mental health is important too. So, I'm just giving food for thought here. Good luck and congrats on the new baby!!
