Hi so I have 2 little ones (one 16 month old and almost 1yr old) they both fight their nap! They were both previously rock at home (but no longer are) they are in desperate rooms with a fan and/or white noise. They will scream all of the nap time which stops anyone from napping. The 16 month old will sleep off and on screaming in between. Any tips?? Should I be going in there? How long do I let them cry? No down time for me is stressing me out and the kids not napping isn't making them the happiest kids either!!
