I can't offer help w/ more then one, as i only have 1 -
I have been taking him to the bedroom for a nap after about an hour of awake time or whenever he makes his first cry
Maybe by this point he is overtired, it could be that less A time is what he needs. Young LOs are overtired in the blink of an eye.
I would also do a search in our board for the Auzzie swaddle, this may help or try the miracle blanket which i used until 7mo!
Hang in there, his brain is working on learning how to stay asleep during the day. Day sleep is much different from night sleep. Completely different process.
When he falls asleep, the first 20 mins are light sleep (with partial awakenings every 10 mins.. looks like a jolt of her body, or some babies will open their eyes completely) After 20 min of light sleep, the body enters a deep sleep. Another jolt around the 30 min mark, and then normally out of the sleep cycle at 40-45 mins and repeat. But w/ your LO the jolt at 20mins is waking him right into consciousness and completely wake. Swaddling if you can and also wake to sleep may help.
Try the wake to sleep technique: set your timer and get in there before the 20min mark. Put your hand on the thigh, top arm, and other hand shielding over eyes to block visual stimulation. Some pressure (not over eyes of course) but not hard. This does not usual work immediately and in the beginning, stay at least 20 mins.
Remember you can only do what you can -
