Why am I getting nervous 😩 iv had a baby already I know how L&D is I know how challenging parenting is as I was a single mom raising her I know depression can sneak up on you with the late night feedings and diaper changes and no sleep and everything else. I wasn't scared/worried at all when I was pregnant with Grace so I don't understand why I'm having panic attacks about my 2nd baby. Grace is old enough to help and be independent and not rely on me to make her food or give her a shower or put her to bed or anything which helps with having a newborn, I have a great husband who I know will be a damn good dad and help out always. I just don't know why I'm so scared! Maybe it's cause we have our own place again/bills and I know money is going to start getting tight and that scares me or what 😔 I have 70 some days till baby is here and as each day passes I feel like im going to fail my kids some how. 1 was easy but having 2 worries me.
