What am I doing wrong? Weaning and constipation

[TensmumT]

My 6 months old has been constipated for a some days now, he's been on lactulose since Sunday, twice a day at 2.5ml. Hasn't made much difference so far. He's mostly breastfed, but has ready brek for breakfast, blended carrots, sweet potatoes, baby broccoli, cauliflower and chicken for lunch, same for dinner. I'm giving him water with meals. I've also tried giving him apear/yellow melon puree, hasn't made a difference either.

Baby is clearing straining when he tries to go, and cries more than usual.
Any advice?
Thanks

Massage? Belly one that is and bicycle legs. And a bath laying there, I put warm flannel on my LO belly and leave it there xx

My HV always said when you start solids it's not constipation it's just solids make them go less frequent 🤷🏼‍♀️🤷🏼‍♀️

wee bit of blended prunes in with the porridge should help things along. I found bicycle legs never really helped mine

Mushy peas always works for ,my youngest and she’s eaten them since she was 6 months old.
Ella’s make a prune pouch and the cow and gate fruit pots are good

Oh and some orange juice to drink at meal times.

Thank you all, I really appreciate the input! I'll be trying your suggestions

I was told 3 meals a day from 9 months old. I suspect he is having too much food. I would cut back to one meal a day and offer only p foods until this is sorted - peaches, prunes and pears.

Natural laxatives to try are

Chicken broth or scotch broth
Pineapple finger food or juice
Prunes finger food or juice

I have used couple sips of apple juice to help too. I have found I go better with apple than orange and same for my kid too.

I think he's probably having too much food.

To much food to soon? Did you start weaning at six months or earlier?
