I expect this is a normal profile for many kids who are 2 years 9 months old, but things just keep getting worse. We have hit a period of serious food refusal, including the few favourites that she has consistently eaten since weaning. Eating got a lot worse between 18 months and 2 years, but we had a menu of a few decent meals she would eat until about a week ago. She's pretty much living on Cashews, cheese, fruit and some raw veg (although would eat bacon or sausages everyday if we let her - we don't, obviously). Potty training started well but hit a wall with complete refusal to use the toilets at nursery (she holds her wee) and pooing herself 80% of the time even though she clearly knows when she needs to poo (she hides and shouts go away, we have had a handful of successful missions to the potty but things seem to be moving backwards now). She slept like a dream from 6 months until 17 months with a few minor bumps when going through a nap transition, but at 17 months she hit the mother of all sleep regressions which included split nights with wakes lasting up to 5 hours and lasted 4 months - since then her sleep has had good and bad periods but recently has become completely unpredictable with bad or good night's instead of periods of a few weeks or a couple of months that are bad or good. The split nights periodically return, and nightmares have started too at times (poor little lady).
It's just all kind of gone wrong at once. It doesn't help that we only get 7 hours of free nursery through flying start and are raising her largely at home while I attempt to hold down my full time (but quite flexible) job, and my husband tries to keep his business going part time. We will hopefully qualify for 30 hours free nursery in January once she has turned 3 (Welsh government don't match the free childcare in England). Furthermore, my husband is now home schooling my autistic step son because his school consistently punished him for actions largely resulting from, and written down clearly in, his diagnosis. We don't earn enough to keep going like this either. So lots of background stress while things have got tough with our little one hitting all these issues at once.
I'm not really looking for suggestions, more just some assurance that the issues she is going through will improve or pass with time. I realise they probably will, but for some messed up reason I still need to hear it from people who have been through it!
