I have had it with my 2nd, 3rd and 4th pregnancies ... but not with my first. I always thought it was probably because I didn't have toddlers to lift while I was pregnant the first time. I am finding now that it is easier for me to sit down on the ground next to my kids rather than try and pick them up. I still have to pick up DD2 sometimes, but I mostly try to only do it when I am sitting down now and not carry her around for long periods of time. It does help (with the tummy pain and the SPD).
