It is better to not assume otherwise about your child's sleep before understanding about the ideal sleep hours.
Before worrying about whether the child is sleeping enough or not, keep following things in mind:
Most infant babies sleep during the day and are awake at night and this could be irritating and exhausting. It is just a matter of time and your babies will settle with the routine.
Some basic ways can help your baby enjoy sound sleep at night and keep them playful during the day:
Sleep walking is common in kids; Most kids outgrow it by they reach their teens.
Nightmares/unpleasant (bad) dreams are common among preschoolers as this is the age when they start understanding about normal fears and their imagination is highly active.
Sleep talking is common among children. It is not as serious as sleep walking habit and it can be resolved easily.
By following proper measures, the habit of sleeping late can be improved upon.
Swaddling gives a very cosy feeling to a newborn baby. The baby feels as if it is still in the mother's womb.
Urinating in bed can be avoided by not giving fluids before bed but sometimes it has underlying psychological reasons as well.
Choose sleepwear in a way that the baby sleeps hassle free and wakes up with a smile.
