I have a 2 year old and a 4 month old. The four month old doesn’t sleep. Ever. He literally wakes up every hour at night. I double swaddle him, but he squirms free. I try leaving him unswaddled, or swaddled with one arm out, and he keeps waking himself up. Not only this, but he has started waking up for the day at 5 in the morning. I am at my wits’ end. I am a human zombie. I don’t know what to do
This has turned me into a terrible mom and wife. I have no patience with my kids or my husband. I am always in a bad mood. I have yelled at my own baby. I can’t take this much longer. Any advice?
You poor thing. I’m so sorry. I’m with you–when I don’t sleep, I can’t function. I actually get sick to my stomach and throw up.
The first thing to do is have your pediatrician check the little one.
Many four-month olds still do some waking up at night, and they are active during the day, sometimes only taking one or two naps.
But most four-month olds are capable of sleeping at least a few hours at a stretch, and usually 4-6 hours at a stretch.
The doc needs to check out the child and make sure that there isn’t a physical problem, e.g., reflux, or colic, or perhaps an allergy to mother’s milk (or formula), that is keeping the child from sleeping.
So please, as soon as possible, have a doc check out the baby to rule out any physical cause for the wakefulness.
Not that it matters, since all babies are different–but what were your first child’s sleep habits? Is there something that you did differently with Baby #1? (Of course you did something differently–you didn’t have another child to take care of back then!

Life was easier!)
Also, I would suggest timing your 4-month-old’s wakefulness and sleeping. You state that the baby is awake every hour. Make sure that’s true. Sometimes when you are exhausted, your sense of time is distorted, and a minute seems like an hour, or a hour seems like a minute. Perhaps your baby IS sleeping for 2 or 3 hours at a stretch, but it just feels like only an hour to you. Of course, a 2-3 hour stretch is not very long, and I’m hoping that your baby can learn to sleep at least 4 hours at a stretch, and preferably 6 hours or more. But make sure of the sleep cycles. It would be helpful to know this information for certain when you consult with the doctor.
(BTW, I’m a 54-year-old woman who has raised two daughters.)
