I'm sure this has been done a million times but DD2 really, really battles sleep during the day. She's pretty good at night (the bath, feed, lullaby etc seems to do the trick) but during the day she gets more and more tired and then just cries and cries (I pick her up, she cries, I put her down, she cries, I rock her she cries, I try to feed her she cries) - have tried dummies etc but to no avail, sometimes she'll fall asleep after sucking my little finger but it doesn't always work and even if it does I also have a toddler to deal with so being bent over a cot with my finger in her mouth isn't really that practical.
Now, on occasions when I've left her to cry (not by choice BTW but for example when she's been in the pram screaming and me rushing home so I can pick her up and give her my finger) she'll literally drop off mid-wail. I hate the idea of leaving her to cry when she's this tiny but when I know it's definitely tiredness and rocking etc doesn't help what other option is there? Anyone found a good solution to this?
