Hi there
Sorry to see you didn't get a reply yet.
At 6 months the most common routine would be an A time of 3hrs and 2 long naps of either 1hr 30 or 2hrs.
Looking at your current routine it's probably time to drop a nap, this might be nap 3 if it's usually a CN or you might drop nap 1 which is already only short, then move nap 2 (which becomes nap 1 !) earlier than it is currently. Looking at 3hrs after morning WU.
I know methods that say the last awake time should be longer??
This is not part of BW. With BW routines are worked out dependent on the individual LO so whilst we have some guidances times and ages we only use those as a guide not a rule. Certainly some LOs like a long A time before BT but many will hate it and it will only cause OT and then NWs. Some LOs like the last A time to be the same as the others with a lot of consistency in the A times across the day and some like the first A time of the day very long and the last one very short. My own DS needed a short last A time.
I would suggest starting with what you currently have, then increasing to get it a bit more age appropriate but also record your EASY times along with LOs mood and ease of settling and sleep etc so that you have a gauge to work out if things need to be a bit longer or shorter for him.
With regards to the night feeds, it is quite normal for a BF LO to feed a few times at night. Make sure you offer all the milk feeds as normal during the day, do not reduce milk at all in the day time. After solids you might like to offer a top up of milk, Tracy suggested this in her books and I found my DS initially needed milk right after solids (mine was formula fed but still needed a milk top up right after the solids despite having already had his fill of milk at his usual E time). Also offer water when solids are offered.
Helpppp he wont eat when wakes up. Only at round 830/9 which ruins the lunch nap because he is hubgry in the middle of it and then wont settle back .
Mine would generally not eat right after waking so I fed 30 - 60 min later but it can still be worked around naps. The main aspect of when to feed is to avoid a feed to sleep habit rather than it being vital to feed after waking. If you offer a milk top up right after the solids you may find he is more comfortable for the nap and not waking for a feed. I would suspect that it may be something other than hunger waking him mid-nap though, possibly routine.
hope this helps. Let me know if you have more questions.
