I totally understand the itch. I think it's because at 14 months they are beginning to do more, nature screams for u to have a little cuddly bundle to kiss and coo over (and somehow we forget the sleepless nights, the hours of pumping that weren't so bad...). I got the itch hence baby number 2

Remember that in this profession there's really no 'good' time to have a baby so take life by the reigns and make another beauty (as long as you have a good support system nearby). Best of luck.
