Growth spurt at 4 1/2 months

Kaitlyn has been waking up during the night and wants to nurse (I am breast feeding). She has slept through the night since 5 weeks so this is not normal for her. How long will this last? Should I increase the amount of milk she gets during the day? She currently has 4 oz every 3 hours. She has also been more fussy lately. I want to make sure she is getting what she needs!

    Usually a growth spurt last a few days to a week, if I remember correctly, but it will probably vary from child to child. If you are breastfeeding, she will be cluster nursing and wanting to nurse every hour on the hour even at night...ususally. I would say allow her to nurse as often and as long as she wants and needs to until she has your milk supply up to where it satisfies her new needs.
    I agree with Theresa.
