This has probably been done to death, but all the advice I read doesn't apply perfectly so thought I'd ask again!
I weaned my 6.5 month old when he was a week off six months (he was overdue and very ready for food). He doesn't love purées and prefers to do baby led weaning. I try and give him a mix of both.
He's breastfed and hasn't dropped any feeds, he's just adding food into his diet.
For breakfast he gets a banana, lunch today was homemade pesto (seeds, basil, olive oil) on pasta. He sucked the pesto off (no salt, no cheese). Last night he had a some veg and some meat (no salt, again just sort of sucked and gnawed away) and I attempted to give him a baby pouch. He had a little, but not much.
Is the sort of food I'm giving him wrong?
I'm sure being constipated at his age isn't a great sign! 
Anyway, tmi, but his poo is small and hard and not soft and, erm, volumous anymore!
