How Old Are They?
1. i want to wean them and i read a couple of methods... which is the best way to go about this.
I know other breeders has other ways but this is what we do.
I start weaning mine at 6 weeks old & they are still nursing on mommy too. I started mine out at 1 time a day for a few days, then 2 times a day for a few days then 3 times a day.
I start mine out on Gerber Baby Rice Cereal (Powdered) 1st for about a week to get them use to the thickness of food, I mixed it with Esbilac Powder I got it from our Vet, (I warmed the Esbilac formula that I already had made up in the fridge before adding anything to it) I had to help hand feed our last litter.
I made it thin for about 3 days (So they can learn to lap it up) I made it a little thicker on day 4, making it a little thicker every day but still kinda soupy till day 7, on day 7, I mixed canned puppy food with the baby rice cereal (Mix u're rice cereal with U're Esbilac 1st then add U're canned puppy food) for about 4 to 5 days, & make it thin to start with, then I add some dry puppy food moistened down with warm water and add that to U're baby rice cereal mixed with the Esbilac then after 4 to 5 days I put in little dry puppy food here & there and then they are on the full dry puppy food. It does take me longer to wean but I haven't had any touble doing it this way. No puppies of ours got the runs, pukes, or upset belly. They all thrived on it & loved it. All our Yorkies was on Science Diet then, now they are all on Nutro and I will do Sages' litter next Spring the same way except use the Nutro. I hope this helps U 
2. x-pen with a DOOR is coming today so i will be moving them from the play pen into the kitchen... its still kind of cold should i continue to use a heating pad?
How cold is it in U're kitchen?
3. i would really like to have them go potty outside... is it to soon to start that... (it will be in the seventies mid week.)
How many puppies do U have? I puppy pad train 1st then just take ours out to play and of course they potty then. I took ours outside when they was about 7 weeks old and they was born June 21, 07
4. is it ok to have dad around them yet. hes seen them a couple of times but for the most part i've kept him away from them. since they will be in the kitchen with him is this ok?
At 6 weeks of age we let ours be around dad too, as we put our puppies in new litter boxes with their food bowls (Each had their own bowls) in them to eat (2 Puppie per litter box so we had 3 litter boxes total in the living room all lined up lol) (We had 6 puppies in this litter so I had to think of something lol) on our living room floor. I really love the large litter boxes to start feeding them in, they keep U're floor clean and U just have to catch them if U can to wipe paws and faces off with washcloths before they climb out. After they got done eating they would go play around in the living room and daddy was in there too, he was scared of his own babies lol. But he got to where he loved to play with them.
I hope this will all help U. I love raising babies, really miss having them, loved getting up every 2 hours to feed and making 6 bowls of food. I got tired but I wouldn't trade a minute of it. I hope U're babies do good!
