My son is almost 3 months old. The first month, he would start out sleeping in a cradle (after I rocked/bounced him to sleep). And partway through the night was moved to his bouncy seat (on vibrate), because he was having trouble with reflux. It helped him to sit up. At this point he was swaddled. Then we ended up getting him to sleep in the cradle again about a month later. Now we're back to him sleeping sitting up, but this time in his car seat. He would give us a 6 hour stretch between feedings in his car seat, so that's where he is for now. My doctor said a lot of parents do that for the first 3 months. Since he is my second son, I need the sleep. No time for mommy naps this time. We do plan on moving him into his room in his crib soon. Hopefully, that goes well. My advice is do what you need to do to get some sleep. Some people have their infants sleep in a swing. When I had my first son, I was all about doing things "right" or "perfect." Now I know that every habit can be broken (even if it is hard, it's possible). So, do what you need to do. We bounce my son to sleep by us sitting on a large exercise ball (saves my back) and then we put him in the car seat. He sleeps well in there because it's cozy, I think. Best wishes on finding what works for you!
