How long 1 tin of formula lasts for +6 month babies?

[ozysanj]

Hi ladies,
I know before solids most babies finishes 1x900 gr tin in about a week.But what about babies who started to eat solids?
My LO is 6.5 months now and I got a good deal on formula on eBay,trying to decide how many tins I would need.
Thanks

My DD2 is 13 months and still has 18oz of formula a day. We usually go through a 900g pack in about 10 days. Once fully weaned, babies still need about 20-24oz of formula per day until they are 1, so I would say that maybe a 900g tin would last about a week, maybe a little more. xxx
