Going by what you've said I'd suggest the following
(minimum of 3hr 15 A time after a nap of more than 40 mins and minimum of 3hrs after a 40 min nap):
WU 6.30
(A time minimum 3hr 15, and get as close to 9.45am as you can for nap even if he wakes earlier than 6.30am)
nap 9.45 - 11.15
nap 2.30 - 4.00
BT 7pm
do I just deal with over tired naps ?
If he wakes with OT naps of say 20 mins use shush/pat or adapted to get him back to sleep and continue to try for 40 mins. If he wakes again try again to resettle. Things can get messy during routine set up but if you grit your teeth the routine will settle more quickly.
He had 40 mins nap this morning shall I keep him up 3 hours regardless of nap times?
At least. In the BW books Tracy kept babies up way way longer than their A time to get them settled onto a suitable routine. We often go slowly on the forums but as you've discovered if you go too slowly you never get to the longer A time and longer nap.
You can use the times above as "set" times for a few days which will get the routine established far more quickly. This might mean much longer than 3hr A time but that's what Tracy did. The tiredness, even over tiredness can help to establish the routine.
Also he is still having 4 bottles in the day and waking once in night for one
My hv said he should have 3 bottles a day and with good times do u give food straight after bottles or in between ?
I would not reduce day time bottles yet. IMO 4 bottles per day is totally normal at this age. Milk is still his primary food. If anything you might consider a NF wean if you feel ready to tackle this (personally I'd wait a bit as you want to get the routine in place and it is quite a lot to take on more tasks just now but it is your choice). In any case I would drop night feeds before reducing any day feeds.
Solids come roughly 1hr after milk feeds. At this age I'd offer 2 - 3 solids meals.
Here's a sample routine based on the above time with the E times added:
WU 6.30
E 6.30
E 7.30 solids
nap 9.45 - 11.15
E 11.15
E 12.15 solids
nap 2.30 - 4.00
E 4
E 5 solids if you are doing 3 meals
E 6.30 BT milk
BT 7pm
NF until ready to wean
we do his last bottle in the bedroom he drinks and is normally pretty asleep when I put him down not fully as he still turns over gets comfy etc and sometimes here him having a little moan do u think this is ok to do ?
Sounds fine
