Hi everyone

I weighed myself today and I’m 1 stone lighter than I was before I got pregnant with my daughter (she’s now 17 months old). This worried me as I’ve never been this weight but could it simply be because I’m running around after a toddler all day and the only time I sit down is if I’m at work or in bed? Just wondered if anyone else has ended up with a lower weight after having a baby? Thanks in advance x
