My best friends little girl is a day younger than L and shes alot more advanced than him in pretty much everything.Tbf I think nursery has had a positive effect on him...he seems way more advanced in his speech ,independence etc than Isla...she comes across as very immature for her age...probably because she's been kept that way for "the gram" where as I feel Lachlan will do better for himself in the long term as he's" the one that got away "so to speak...but that's still no excuse for not including him in family life
You can hardly understand him when he speaks snd its normally very short sentances.
