My 15 month old daughter goes to sleep keeping herself latched to mother's feed. When she was a newborn, she used to sleep in a crib, but she has made a habit of going to sleep with milk latched from about when she was 3 months old.
From last 6 months, her sleep schedule is:
Wake up time - 4 hours
Sleep time - 2 hours
Then, wake up time - 6 hours
Then whole night sleep - 12 hours (with latching on and off as per demand)
Now the problem comes when sometimes she over or under sleeps in the 2 hours day-sleep she takes. Then she won't like to sleep in the night. This episode happens once in a month.
Earlier, we used to play with her and after about 8-9 hours of wake time, she used to go to sleep.
But as she is growing, she gets very fussy after staying awake for about 9 hours. Boom! Now it has been 9 hours since she slept! Now she is super cranky, she won't take feed, won't sit or lay down on bed. Won't like if we switch off lights.
We massage her body and head, sing songs and do other things to soothe her, but this will just distract her from crying. This doesn't relax her.
We can see that she wants to sleep, but she is so tired and cranky that we won't be able to relax and feed and sleep.
Last time she was awake for about 14 hours, after that, she was too tired and slept.
She has gone through breath-holding spells 2-3 times. That's the reason we don't let her cry much nor leave her on the bed unattended.
But it gets very difficult for us now especially in the COVID lockdown time.
The doctor has suggested Phenargan. (Also we want to know the trade-off between sedating her versus letting her super cranky for so long hours.)
We want to know what else we can do rather than sedating her.
Also, she hardly likes her car rides in a normal mood. During her overtired phase, she just hates to sit in the car. Most people take their baby to car ride when their baby won't sleep.
