Overfeeding a BF baby ???

[macdoodle]

Is this possible....DD2 was 8lb12 at birth didn't really drop any weight, was 9lb2 two weeks ago, and weight today 10lb15
So she has gained 29oz's in 2 weeks, and over 2 pounds since birth she is 3 and half weeks...
She BF really well but fairly frequently with evening clusters sometimes but on ave 2-3 hrly in day and 3-4 at night...am worried that I am overfeeding (she looks lovely and chubby) and missing comfort/sleep cues as hungry??
Any thoughts or should I just carry on - am quite chilled with BF this time (was very hard with DD1)...this time am happier just to sit and feed if need be and stuff the house/chores/getting out etc ...even DD1 (age 6) will just sit and read/watch Tv etc while I feed....

Ds was gaining that sort of amount at one point - he was prem (35 weeks), born at 6lb 5oz, and weighed 10lb 10oz on his due date. And he did drop quite a bit in his first week.
You can't overfeed a bf baby - they will eat as much as they want, and often flatten out their weight curve at 4-6 months.
