How did you handle changes in relationships? (semi-rant)

I delivered 6 weeks early a 5lb 15oz lil boy:)  After spending 2 months on bed rest in the hospital and Mason spending 11 days in the NICU, we're both home and doing great!  Mason is getting bigger and gaining weight like he should.  Now it's my turn to lose this weight!  It's tough to get back on the band wagon...I CAN do this!
