1. Your baby will be on her own schedule for a few weeks. She will likely sleep for 3-5 hours at a time and will wake up to eat and for a diaper change. She will probably spend around 15 minutes awake at the most. Don't worry about a bedtime routine for a few weeks. Once she's spending more time awake it will be easier to set a good bedtime.2. If you rbaby has reflux she will spit up a lot, will scream and cry after eating and may even stop eating because of the pain. Some amount of spit up is normal for all babies, just make sure you burp her after each feeding. Also make sure you don't overfeed her. She probably doesn't need to eat every time she fusses or cries.3. It's really not that hard to care for a baby. She'll be sleeping most of the time and you should sleep as much as you can at the same time. Don't worry about cleaning and cooking or anything like that. You need as much rest as you can get. At this point all she really needs is to be fed, to have her diapers changed and to be loved. You'll get yourself into a good routine soon enough.4. Diaper rashes can get infected if they are left untreated long enough. Diaper rash is generally red and may be blotchy. If it isn't treated right away it will get bumpy. A natural diaper cream like Method or BabyGanics works well and isn't likely to cause any irritation because they're made without harsh chemical ingredients. If you suspect your baby has a diaper rash you should consider using natural diapers and wipes. I like Earth's Best. I've used them for all three of my kids and have not had a problem with diaper rash (except when my son got thrush).As far as any allergies go, she probably won't have any allergies that you or your husband don't have. If she does have an allergy to dogs she will likely have watery eyes, sneezing, or breathing problems. But, studies have shown that pets in the home during a baby's first year dramatically decreases a child's chances of developing allergies to animals, pollens, etc.And, in my opinion, everything is pretty easy when you just have one baby. It's true that you'll have a lot to learn to figure out but you have plenty of time to learn. I just came home with my third baby and things are pretty crazy!
