Gosh that sounds very overwhelming for you
. 9 months without 5 mins to yourself is very wearing, and it can feel v worrying when you feel your baby should be eating more than they are. I second (third?) the suggestion of the book "My child won't eat" by Carlos Gonzalez. It's very reassuring
.
This article on "velcro" babies and toddlers has been reassuring to me at many times when I have felt completely stifled by one child or another's constant demands. It won't always be like this.
One question to ask if you're very tired, is what will get you the most rest at night? It may be that taking on a big change (like stopping feeding at night or switching to bottles in the night) might actually lead to more battles and less sleep for you. Sometimes, for some people, just rolling with it, or mentally agreeing with yourself to 'review' things in a week, a month or whatever can give them permission to just say "yes, I'm exhausted, but this will pass and I just need to do what I can to get by for now". Not sure if that makes sense?
Is there anything you can do to get more rest? Can you put your head down for 20 mins whilst she has a nap during the day? could DP/DH get up with her in the morning occasionally whilst you get 1-2hrs of good quality sleep alone? Is it just you and her co-sleeping or DP/DH as well? If the latter, would you sleep better with them in a different room for a couple of nights (or vice versa)?
I agree that the independence thing is probably not especially related to method of feeding, but more likely to be a personality and age thing. I've found all of mine much more Daddy-friendly from 18 months-2yrs onwards, but the clinginess has varied between children and manifested in different ways at different times. At the moment, she's probably just figuring out that you are a physically separate person from her, and that might be a bit scary, hence the need to be v near you constantly. How does he feel about her reactions to him?
Things will be different when you're at work, she is bound to eat and drink something when you are not physically available. There will be a time of transition, but she will get used to the new arrangements. I know it's hard, but try not to panic too much about that in advance. It is very difficult to predict and plan what will happen
, even when it is fast-approaching.
