Kellymom says: "Common times for growth spurts are during the first few days at home and around 7-10 days, 2-3 weeks, 4-6 weeks, 3 months, 4 months, 6 months and 9 months (more or less). Babies don't read calendars, however, so your baby may do things differently."
DS wanted to eat almost every hour but he was so sleepy that he would fall asleep only minutes after starting to eat. It was a challenge but only lasted about one day.
Re: 6 week growth spurt?
The growth spurts can occur at any time.
