Good sleeper gone bad!!!!

Kelly • Mommy of 6, should we make it 7?!?!

3 months and she generally used to sleep ok. She would nap for up to a 5 hr stretch during the day and I could accomplish ALOT. During the night it was 3 to 4 hrs at a time. Idk what the hell happened but she WILL not nap during the day longer than for 20 minutes at a time. Nights have been a hit or miss. Last night was great, she woke 2 times and went back to sleep fairly easily the night before was pure hell! Anyone has a good sleeper who has made a sudden change? Is it normal at the 3 month mark? Im going nuts, I have so much to do and she just wants to be held all day. She hates her carrier so wearing isn't really an option sigh. Help lol.
