We have a 3 month old boy and I am still not entirely comfortable with addressing and refering to him by his name. I do make a conscious effort to use it daily, but it still feels a bit weird and doesn't come as natural to me as baby, sweetie, etc. With my dd1, her name suited her straight away. With dd2 it took a few weeks, I can't remember how many, but was def less than 3 months.
Just to add that his name was not my first choice, in fact it wasn't even on my list, but I was talked into it by dh. I dont know if that has anything to do with it.
Anyone else had similar experience? Will he ever grow into his name?
