My very good friend is distraught over her nearly 6mo DS's sleeping habits
Can anyone offer some advice please? I've run out of ideas.
He goes to bed in his own room at about 7pm, friend or her DH try to put him down semi-awake. If he goes to sleep he often wakes up 5 minutes later and then takes a lot longer to settle.
He feeds normally twice a night (ff due to problems bf) but then stays awake after one or both feeds for an hour or so (this is the bit that is killing my friend - being awake each night for so long).
His naps during the day are also pretty difficult, and because he's so tired after a bad night's sleep he struggles to nap properly too.
I've suggested the 'do whatever it takes' approach but it doesn't seem to have any effect - shed tried rocking him, not rocking, patting, co-sleeping...She's getting upset at the thought that nothing she does is working. 
She goes back to work next week too, so really needs to get some decent sleep.
Some of it may be standard 6month old stuff/developmental, but it's been getting steadily worse and worse. Her DS has suspected silent reflux plus various food intolerances, which may or may not be relevant.
Any suggestions?
