My 6.5 month old dd has never been good at napping during the day, gets overtired easily and spends large amounts of the day grisly. I started to see an improvement in her napping when I switched from ebf to formula at 5 months and again when I started dd on solids at 6 months. The difference was amazing, dd was so much happier and wanted to play, smiled and laughed etc.
However the last couple of weeks it's been back to being awake and grisly all day. I make sure I look out for her tired cues, yawning etc (which at the moment is all the time...), make sure she is well fed, winded, clean nappy, sing lullabies, dark room, warm enough etc. I've tried co sleeping, pram, car seat, sling but she won't sleep in any of these ( some times in the pram for 15 mins or so and most of the time not even that). The only place she was ever able to have a proper nap was her cot.
I think she's teething so have given calpol but it made no difference.
The mornings are ok-ish as dd can survive on no sleep but by 2pm she is so tired. Every afternoon in the last two weeks has been spent either doing shush/pat in the cot (using the dummy) or, when that doesnt stop her crying, holding her in my lap in a dark room till tea time. Neither makes her sleep but doing anything else produces a meltdown.
I feel I'm failing her and find it so upsetting. Where am I going wrong?
