How long would/ did you let a 4-5 month old nap in the day time? I used to never wake her from a nap but recently her night sleep has gotten so bad I wonder if I’m letting her sleep too long in the day? She will often sleep 2 or 3 hours on me if I don’t wake her (although by then I often have to as I need a wee or something to eat).
Could the long naps be affecting her night sleep? For some context - she showed promise of sleeping through the night before we hit the 4 month sleep regression, then it was back to every 3 hours. She was then managing a 5-6 hour first stretch but the last few days she doesn’t seem to settle at all for most of the whole night (but could be due to teething and she has a cold at the moment).
