Frequent night feeds in 6 month old - am begining to lose the plot

[VotePedro]

DS lulled me into a false sense of security at 3 months when he started sleeping for 6 hours without waking (bliss) this all ended at about 4.5 months (my short term memory is shot so am taking a stab at lengths of time etc) and since then his night time feeds have been pretty much every three hours with some intense growth spurts when feeding every hour or so at night. He is now 28 weeks and for the last three weeks or thereabouts has been feeding every two to three hours at night. E.g last night it was 23.30, 2am, 4.30am, 6ish, 8ish. We started solids at 26wks and whilst he is eating enthusiastically (BLW so all sorts of things really) it's clearly made no difference to his nighttime hunger. He is big (around 21 lbs) and growing well. I guess I just want some light at the end of tunnel that this might end soon. I'm not even expecting him to sleep all night but more than three hours in a row would really help my sanity.

Does he get near to 45 minutes?
With DS2 it's sometimes exactly 45 minutes, but if less than that I try to get him to go back down, if it's roughly 45minutes then if he wants to get up, I let him get up.

Around 40 mins usually - some tims a wee bit more or less perhaps - I am a bit crap at timing these things! I think he is getting a bit better at day time sleeps and I have managed to resettle him a few times of late. I usually have a go unless he is stark staringly awake.

I'm sure not every child has an exactly accurate 45 minute sleep cycle Would seem a bit mental as absolutely nothing else in nature is so specific! 40 minutes is probably his length of time wouldn't you think?
