how can in 1 day she go from 4 naps to 1 a day

[livysmum]

hi. another nap question.
DD is 7 months old, 3 days ago she was napping at 9:30-10:15ish then like 12-1 then 3-3:45 and sleep at 6:30 7 ish
BUT NOW
SHe rubs her eyes when shes tired and cuddles in and now shes all of a sudden when I go to lay her down has a huge cry like the one she does when shes in pain like wind but when I try to wind her nothing comes up and she wants to play again.
It's just so hard now to keep her happy because shes overtired and games only intrest her for a short while before shes rubbing her eyes again then still wont sleep when I put her down. what is she playin at??
She may be having a growth sput because she is drink lots more milk, no sings of teething (like hand in mouth or drooling)
i'm pulling my hair out trying to keep her happy.
help!!

i think at that age dd1 used to have morning nap around9 for around 1.5 hours and afternoon nap at 1 for 1hr (normally 40mins) tops and be around 6.30.

Sometimes I would have to put her in cot and let her cry a little and then she'd nod off just had to adjust her for a few days then she was fine

excuse typos feeding dd2 and typing

ok just gave her a bottle and she fell asleep on that figers crossed that it lasts a while

My DD is 6.5 months and is also undergoing a napping change, she had maybe four naps before but has taken to doing two and last week we had one day of a 1 nap. She gets very tired and grumpy by the afternoon and I've tried everything to get her to sleep but she fights it. It feels like it did 3 months ago when she was definately sleeping less than she needed but she got through that so I'm hoping this is just a stage too.

The only way I can keep mine happy is to hold her which is increadibly frustrating but I'm going to get a soft sling and hope that helps.
