8 week old sleep routine- 😴

Jess. • Connor James. 14th July 2016. ❤️
My 8 week old is a great sleeper. He sleeps an 8-9 hour stretch at night and then sleeps 5-6 hours during the day (which roughly equals between 14 & 15 hours in a 24 hour period) he had been pretty consistent with his napping during the day, usually napping for between 1 & 2 hours at a time at roughly the same time every day, but for the past few days he's been "catnapping" during the day. Which means he will sleep between 15-45 mins at a time and nap much more frequently than he would if he was having longer naps. It still works out to be between 14-15 hours of sleep in a 24 hour period and it doesn't seem to be affecting his night sleep- but is this normal? Any advice or input would be appreciated 😊 (Sorry if this doesn't make sense- I tried my best) 😝
