RE milking mum.: If her udder is quite full you will have to continue milking her, it may be quite difficult to dry off a BS x BT a week post-kidding without seriously risking mastitis.
I start mine off on the following regime.: Off the dam for a few hours to make sure they get hungry, then into my daily rota of 7am, 12noon, 5pm and 10pm. Basically they just start whenever the next feed is due. I start off with 150ml per feed and if they finish that for two feeds in a row easily they go up to 200, then 250ml until full bottle about 2 to 3 weeks in (my GG's take a little longer to get to full - 500ml - bottle stage). (I have no idea how much 12oz are - sorry, I am genetically programmed for metric
There is no point trying to feed them more than they would take, and also once I have messed around with them for 10 to 15 mins I stop. They will get another chance at the next feed. If it gets to evening and they had less than half their planned daily total - I make sure that the last and first bottle are tube-fed, but let them get hungry during the day. That's especially for the night feed, I don't want them to go cold.
Obviously any that are weak/not quite right etc will a) get more feeds offered and b) probably come under a lamp if I think it necessary, or preferably come into the house (dog crate) so I can keep a close eye on them and feed (if necessary by tube) more often.
I have also found having the milk a bit warmer is usually better than a bit cold, they really don't like cold(ish) milk at that age. Try a sock or two over the bottle to keep milk warm if they do take a bit longer or have breaks in-between.
One thing that I have found works a treat, is to milk some colostrum from mum straight after kidding BEFORE the kids have suckled and offer them the bottle straight there and then. They normally take about 100ml of colostrum quite well, and then go on to drink from mum. I also then don't worry so much about them getting colostrum. Whenever I manage that, the transition from mum to bottle is really easy - I don't know if it is that they remember or what.
Hope you can get the little men sorted! Does the dam stand up now?
