I found it difficult to feed my DS a dream feed by breast at 10pm so I started with bottle. I use the milk I expressed in the morning, which I had stored in the fridge. I would take it out about 10-15 minutes before the feed just to take the real cold out of it but he had no problem taking it. I never really had an issue with nipple confusion either he just seems to take whatever he is given!! Try a very slow teet on the bottle at first though and take it nice and slow!!!
What I did re morning time was eg; if I was feeding on the right breast, I would feed baby, then make sure the breast was empty with pump and then empty the left breast. then on the next feed, 3 hours later I would offer the right breast, next feed right, next feed left etc etc. I would get about 6oz & I would store this in the fridge as I said above. When DH feeds the baby at 10, I then sit and pump again, generally I would only get about 3 oz or so here which I was freezing, I used this milk on days I was out, or a day that I wanted a break to relieve a sore nipple etc etc.
So thats hat I was doing, hope its helpful, let me know how you get on and post again if you have any problems xx
