Jaapie,hun it sounds like your doing all the right things hun,it`s just the age difference and wanting your attention all the time,I think most of us have been through this before and although it can be very stressful,you must just stay firm with what you mean,they do out grow this,but sadly some kids just seem to want more of mummies attention than others.Our 2 year old is a terror atm,he wont leave our 9 month old alone and takes away all his toys,we are firm with him and make him go and give them back,but to be honest he is so jealous of his brother i wont leave them alone in the same room together,as our 9 month old is just starting to crawl,he enjoys plenty of floor time but i can`t trust our 2 year old as he has tried to run over him with toy trucks,pull his arms and legs,things will improve hun,try and stay strong,kids are always testing us,ay!!! take care and here`s a big try not to get upset,it`s all part of parenting,lol.but they do know how to push our buttons sometimes.
