Solids/poops

We started introducing purées at 5 months (ped okayed it at 4 months but we waited).

We’re about 2 weeks in now, my daughter was EBF before so would have the BF watery poops but since starting the solids she will pass 1-2 ‘log style’ quite firm poops (sorry TMI) followed by a watery breast milk type poop.

Is this normal? There’s a very clear difference between what she will pass and it seems like it alternates every 2-3 nappies.
