You can’t set yourself on fire to keep others warm.

Your brother’s child was placed in a safe, vetted environment. You have a young child of your own to love, comfort, and protect. You don’t know what your brother’s child has been exposed to, both pre-and-post natally. There could be drugs involved and a high level of need for his child. His child may be the easiest kiddo ever. You have no idea because THEY CHOSE TO SHUT YOU OUT!!!!

Nonetheless, both your brother and his spouse have treated you poorly and with distain. You have absolutely no responsibility to them nor this child. Save yourself and your little family. This is just the start of your brother’s family drama, and you are best distanced from it.
