I think the limited plastic toys lasted till Grandma went shopping,
The no sugar lasted till DD discovered toast with jam, but she only eats that once in a while.
No dairy till at least a year, turns out she loves yogurt and cheese, she really loves cheese.
Planned to BW all the time turns out DD hated the wrap I got but I made a Mei tai and use it when shopping, it was awesome in Mexico.
Wanted to start saving $ for her, so far she is almost 10 months and haven't saved more than a few dollars.

I did EBF till 6 months and plan to continue BF till at least 2 years I would love to try BLW but I have to family support for that, they all think that 6 months to a year is plenty, and have desided I'm insane.
Started cloth diapering at around 3 months and started EC at 6-7 weeks together they made an awesome pairing for me.

I'm sure there is more thats all I can think of for now!!
