Is my Son sleeping too much?

Hi Helen

I have a wonderful boy, 2 1/2 months old, and I am pretty sure that he is thriving well. He sleeps and eats really well. Maybe he sleeps too much. He has a 45 minutes' nap 4 times a day. I settle him for the night at 09pm, and he sleeps until 08am the next morning ... My question is whether he sleeps too many hours without having a milk feed. He is bottle fed, and has a bottle every 3-4 hours.

Best regards
Nanna
