Im hearing you on being the heaviest ever. Summer last year was sooo hard

I found that around the time that MJ was 5 months old the weight started to come off easier.
I am almost at pre pg weight (but dont look it, i have the suspicous looking tyre that has wedged itself under my skin!)

I try and go for an hour's walk 3 times a week, sometimes more and only recently i have set my alarm to get up before MJ and DH and i do a pilates DVD or hop on the wii fit for 30 mins.

Try not to drop your intake like the other girls have said as your BM will suffer...
Its not like when you are pg where the baby will take what it needs, if your dont eat or drink enough your supply will be affected.

Rememebr the weight goes on in 9 months, so dont expect it to come off quickly ... 9months on 9 months off - thats my rule
