Hang in there this too shall pass.
Someone once told me this when I was feeling guilty about my time not spent with my son….
Your other child had your undivided attention for 4yrs and did not have to share you. This new child will never have that opportunity so don’t feel guilty about your time that this new baby needs.
The new baby needs his mom right now more than ever you are the only one who knows all the things he needs! Trust your instincts you are doing everything in your power to make sure he is comfortable and happy never doubt yourself. I know it is hard to figure this crap out!! I have done more research and reading on the internet that I want to puke. Talking on this forum (which I have never did before) was really helpful for me to know that I am not crazy and not alone.
Would you say he is stable now?
