I'm early days with second pregnancy, and have a 19 month old. I sometimes have her in a pushchair and sometimes carry her in a baby carrier.
Had terrible SPD last time, so want to do all I can to prevent/ reduce it this time. First logic tells me it's better to push that apply the extra weight of carrying DD, but then on the other hand I know you're advised not to push heavy things (eg trollies), so I'm confused which way to go! Help!
