Use within 4 weeks

[Lushwirral]

My LO is five weeks today and she is 85-90% BF, but I give her the occasional bottle when she is very unsettled, which has only really been 5 or bottles a week. Because of the low usage, my tub of Aptimil formula is still nearly 3/4 full, however I read on the side of the box that it should be used within 4 weeks, with my 4 weeks up today!
I don't think they make smaller tubs and I don't really want to throw it away -do you think it would be ok to use for another couple of weeks?

Hmm not sure on this, my tub always goes within 2 weeks! Why don't you buy the cartons if you're only using occasionally as it'd probably save you money and you don't have to worry about expiry dates xx
