sorry you're having such a rough time with your nb. I completely understand as my first baby was so, so, so hard. I've since had another baby (only 8 weeks old) and I kid you not, she is textbook (aside from her inability to bf) but I will take 5 of her over what I had to go through with DS. I also suffered horrible pnd with DS so that made things 100 times worse.
how do you feel within yourself. Sleep deprivation is horrific and was the crux of my pnd. i just want to make sure you are looking after yourself as best you can atm. My DS never slept. ever. Total 1-2 hours max in a day on a good day, broken up in 10-20 minute lots. And I was up on the hour overnight - roughly 5-6 times for 12 weeks. Was very rough so I read through your posts and can completely understand.
I see youre in brisbane, have you looked into having a week stay at nurture centre if you have phi. I went their recently with dd to help with her feeding. You need a referral from a dr, either you're ob or pead or GP. Or When you go to child health ask to get put on the list for Ellen Barron too if you think a week stay will help you. I did this and got into nurture centre within a week, I got bumped up the list as a priority cos it was bf issues. Ellen Barron had a 3 week wait so I chose nurture centre.
I really think a week stay with supportive nurses will help you greatly. You will learn settling tips, they can maybe pinpoint specific issues wit your ds (a pead checks babies over on arrival) and youll be able to get a lot more rest.
