I need to vent :/

Okay so I'm getting really sad , I have an almost 10 month old !! This time last year I was so pregnant and would have done anything to of had him here , and now that he's here time is flying ! It makes me so sad . All though I'm so happy at the milestones he's Reached .. And how he is growing and learning , but it just doesn't  seem real ! It does not seem possible that in two months I'll be a mommy of a toddler ! Not an INFANT BUT A TODDLER !? What happend to my new born ! I would do anything to expirence my pregnancy and labor again I miss it so bad ! /: TTC baby number two has been so difficult vs with him it happend completely unexpected .
