My wee boy is very nearly 5 months old and is a good sleeper at night. However during the day he only has about 3 naps lasting about 40 minutes each. I keep reading that his naps should be between 1 and 2 hours. He doesn't seem to be suffering from overtiredness before he goes to bed at night. For context he goes to bed at 6.45pm and is usually asleep within 20 minutes. He wakes for a feed about 10.30pm then sleeps until about 4am for another feed and change and then sleeps until 7.30am. He naps about 9.30am, 12.30pm, 3.30pm and then is awake until bedtime. Should I be trying to get him to nap for longer than 40 minutes or just accept his short naps and be grateful for the decent sleep we both get at night? Thanks!
