We finally got Gideon on a sleep schedule last week. At four months old, it was about time. Needless to say, things are a little more manageable as a result. He is still pretty horrible at taking the bottle but has now moved to solids once or twice a day so now I'm doing alot of breastfeeding and some cereal with mashed fruits. I would have not had a problem with using a little formula to supplement, but the torture of trying to get him to take a bottle is just not worth the toll it takes on our nerves, his disposition and our marriage. He naps 10- 12 and 2-4 and I am making sure to wake him up at those times so he sleeps through the night as well (save the one 4am feeding still).
Also, the potty training is going GREAT!! I highly recommend this to anyone with the time to be around the house with the newborn to give it a go. Ping me for more details.
