Hi guys
Okay so I know babies patterns change all the time so just after reassurance that we can work with this, up until 3 days ago my dads was awake a lot through the day going down for final sleep around 12 (colic/purple time preventing him any earlier) no it's gone until about 2:30 to 3am and sleeping most of the day, I'm not sure if oh overstimulates as he does the shift 7-12 with him so I can get some guaranteed sleep, is this a phase or more effort to keep it quiet at night? Is it possible that babies can go back to not understanding the difference?
