When baby sleep they grow too!
Many pple said need not wake baby for feed but i also sleep feed my dear son.
fyi my dear son now wakie for milk, play 1 hr then will need to sleep. Sleep for about 1 hour or so, sometimes shorter, then wakie 1 hours plus need to sleep again.
2 mths plus i think sleep is still very impt. Be glad that she is sleeping and you can have your own time.
