I sent the lady having her first baby that book ''the effects of love, nurture and play on your child'' or what ever its called, and she said she really enjoyed it, i also told her about gentle parenting and if she wanted to chat about it ever then id love that, but thats about as far as i feel comfortable going, otherwise id feel like im pushing my views onto her and i be being hypocrytical as i emailed her a week ago and told her that no one else can tell her how to parent and that she should listen to her baby and follow her heart, but that includes me.... she feels she is doing the right thing and i guess as long as its done with love it shouldnt matter. i still find it hard though. i think i will just keep answering her questions and comments with tales about what we did and what worked for us, but say that everyones different in the way they do things, at least then im giving her the option to talk about it if she is interested. i want to stay involved with these friends so mot keen to block thier comments, its my issue to move past rather than ignore.
thanks for the possitive replies, i felt so bad about how i was feeling, i was sure someone would tell me to stop being so harsh and judgmental. its good to know that others have struggled with this sort of thing too.

ETA: looks like i spoke to soon. Misty. i totally agree, its not my place to judge them atall, and thats why i posted, because i was finding it hard to get past those feelings and felt bad about it! i know they love thier kids and would never imagine otherwise, i know they have happy children and are good parents, but i STILL find it hard to think about these one week old babies being left to CIO. i talk to these friends alot more than just reading FB status updates and go out of my way to make sure i dont say anything that would upset/hurt/make them feel judged.
