Unfortunately with the seasons change & the birds starting at 5.30am that is my normal time to wake up in spring/summer. I generally put Matilda to sleep earlier during that time so she has a good nights sleep & we have earlier naps too. Last spring/summer she was just over 1 & there was absolutely nothing that changed it. We regulated the temp in her room, we put up black sheets over her curtains & blinds, and we put music on non stop overnight... We even started giving her another bottle just on waking & trying to settle her back but it hasn't worked yet... Sorry.
