My 19 month old baby boy is still not sleeping throughout the night and keeps waking up frequently? somedays he cries, somedays he doesn't. Any reason or anything that will help him to stay asleep during the night

A. If you’re still breastfeeding the child sometimes it is just associated with that whether child gets hungry or willing to take breastfeeding and then crying associated with stomach pain as well as hunger but if you’re unable to figure out anything and facing a lot of issue then check with the doctor
