DD is 5.5yo and DS is nearly 3yo.
I find I am quite often torn as to whether to only let both of them do things that are age appropriate for DS, and then feeling sorry for DD and letting them do things that are appropriate for a 5yo IYSWIM.
For example, DD has got into Ben10 and Transformers, and both of them watch it even though I feel it is probably not suitable for DS age-wise. At 3 DD only used to watch cbeebies!
Also, DD often wants to cycle outside the house, and I end up saying no because DS is too young to join her (if I am not free to watch him like a hawk), and gets really upset if she goes out without him.
How do you find a middle ground with this? I feel I am just being unfair to both of them!
