I didn't read thru all of the posts in your post about anxiety but I wanted to add that I EBF and we used a mini cosleeper that attached to our bed for easy checks to make sure she was breathing-literally an arms reach away (it was $149) and as for SIDS peace of mind- the best $120 I've spent on baby stuff yet was the Snuza. It clips to the top of the diaper and if they stop breathing for 15 seconds it vibrates, if no movement after another 5 seconds it sends an audible alarm. I use it every night Bc even with a video monitor I can't tell if she's breathing in her crib.( we just transitioned her to the crib)
Sorry if people have already made these recommendations already but like I said I didn't read all the posts
Re: **tamb**
this is why i didn't get them. when i realized i was staring too hard, too often at the video monitor to see if she was breathing, i turned that off for a couple days too. the not knowing somewhat unexpectedly gave me more confidence.
fwiw, you sound to me like a regular old new mother with regular old new mother concerns.
