i know this is hard(makon is 2.5 and doing this to)
do you have tantrums(silly question i know) but i know makon copies so much and learns how to deal with thimgs from us so if i have a bad night where i have a tantrum(yup grown women have tanties to) it takes a few days to undo the negative effect it has on him(iykwim)
i also am not liking this stage with makon it is soo hard and i question my self and my ways daily!

a great tip i was given was that toddlers need time to get ready for the next'thing' in there day, so if you want to change from playing with dolls to reading give them warning 'in 5 minutes we are going to pack up then i want you to pick a book and we will do some reading'
they need choices to so if she is fighting over her clothes give her a choice of 2 outfits that you have chosen.

but i guess most importantly talk to her tell her it makes you feel mad angry sad that she is yelling at you(this is when you cant be having a tantrum back) that you would like her to use an inside voice and tell you what she wants not screaming about it.

Your a great mum nessa! toddlers are hard but it is just a phase!! it will be over(then you will wonder where those years went and hopefully you wont have spent the whole time arguing about toys with her and had a few good moments)
