The DIL has been blamed for alot when she's hardly been mentioned. We don't know if her labour went smoothly, if it was rough, if she was ill, how she's doing now, if she's struggling, if she had natural, c-section...
If she was induced I can only sympathise with the process that she had to go through which We know lasted 2 days if not longer...Things up your arsehole, up your vagina, being on a drip, a catheter, blood tests, monitoring, assessments, being prodded and poked, possiblely shitting yourself when pushing...
Then the faf of afterwards when you've actually had the baby...More blood tests, the come down from drugs, the bleeding, vomit, breastfeeding, not sleeping for days, the stitches, the hormones crashing down, baby blues, your womb contracting back to its normal size...
I wanted my mom too.
The poor bloke having to witness his wife go through all that and then hearing his Mom is 'devastated' she didn't hear about the birth sooner.
I wouldn't confront your son at all. Poor lass hasn't even had her 6 week post partum check up with the midwife.
