Baby Poop Query

Hey Ladies! My little one is 6 months old and has recently started purées and mashed food. He doesn’t have more that 50-60 ml of these per day. He has even started having stage 2 formula.

I’ve been noticing in the past week that his poop is different - which is obvious due to the addition of solids. But another thing is that his poop comes out hard in the beginning (rolls of the diaper), followed by soft mushy poop. He strains in the beginning when pooping, no sounds or crying, just makes funny faces.

At times I need lift his legs up to let it all out.

Is this normal?

Thank you for your help!
