Hello Hetal,
My son is 8 weeks old. His birth weight was 5.15 oz and his height was 19 inches.

He is on Breast milk with one serving of formula in a day.

My queries are :
1. If I express milk, how much of oz's he should be having?
2. The same query is for Formula, how much he should be having?
Right now, I am giving him 3 oz of expressed milk as well as formula. I am not sure if the quantity is ok, though he takes it.
3. Till he was 5 weeks, he used to demand. But these days he doesn't demand, so..I feed him every 2 1/2- 3 hrs. Is this allright?
4. He wets his diaper nearly 7-8 times with 2-3 stools in a day. Is this fine?
5. For the past 2 weeks, he sleeps for 6 hrs in the night. Should I wake him and feed him or leave him.

Thanks Hetal Hetal replied. 8wks=2mnths,,,a healthy baby boy,is expectd to take as below in 24hours,,,,
--if totly on Breastmilk - 6-8feeds or more on demand.
--if totly on formula - 6-10feeds of 2-4oz each depndng on his intke at diff feedss.....
-- if on breastmilk and formula, make sure offer breastmilk as often as you can or as much as pssble in total no of oz and the rest alter with formula.
-- make sure to offer both seprtly rather thn mixng it togethr so that one fine day even if bm supply reduces,,your child is very much familiar to formula which in longer run will be better thn strugglng with him to offer formula only..
-- if on bm and formula, make sure to offer formula in daytime,mostly in noons or noon,,to avoid ne gas or reflux probs at night or ne discomfort issues,,that formula might cause.
so this explain,,point no 1,2,,,,

3. now that he is 2months already,,he will demand like 2-3hours or so,,if not,,its better to feed him,,as far as he is acceptng,,its good...once he completes 3months in total,,start reducing night feeds ! for day time feeds,,make sure the time does not go more than 5hours..upto 4-5hours,allow him to demand on his own !
once he will be 3months,,you can go by below feeds :
3-4months : For BM : 5–6 feedings or on demand,,as oftn as required.
For formula : 5–6 feeds of 4-7oz each ! in short, his intake per feed will increase gradually,,expect that…around 3rd month or so,,,,proceed for solids ONLY if, your dr tells you to do so,,,otherwise,,make sure to stretch as long as you can for formula or bm all upto 6months !

4. He wets his diaper nearly 7-8 times with 2-3 stools in a day. Is this fine?
Reply : yeah,,its normal ! good you are keeping him well hydrated with your proper diet and ensuring his proper feeds ,,on time..
Once he is 3mnths old,,,whenver you feel his lips are gettng dry,,or he seems to be suckng his fist or fingrs,,offer some bm or formula say 1-2oz,, and just a couple tsp of cool water (not cold or chilled),,,

5. For the past 2 weeks, he sleeps for 6 hrs in the night. Should I wake him and feed him or leave him.
Reply : now that he is 8weeks/2months old,,and has entered 3rd month,,let him sleep thru out for 5-6hours,and after that make sure to feed him/wake him and feed him,a full feed..so that he does not remain hungry...you can prolong this time further to 8hours sleep,,when he completes his 3rd month...
all looks good, and you are keepng him well hydrated,,keep it up !!!
to check whther or not your child is takng proper feeds or not,,esp if before 9months,,his wweekly wght will reflect it very much !! so consider that,,and ask your dr about milestones,feedng and such other development charts,,so that you can monitor your child weekly as required...
good luck !
good luck...
