Four month routine?

[AlviesMam]

What time do your four months old go to bed? And how many naps during the day do they get?

At 4 months my DD would have 3 naps a day (usually 30-45 minutes) and would go to bed between 7 and 8pm!

My little boy is nearly 5 months, some days he has 3 naps, some days 4 naps. All between 30-50 mins. Some days we get longer than 1 hr. he goes to bed between 6.30 and 7.30 depending on what time his last nap ended.

My little girl is 17 weeks. She has 3 naps a day (usually 30-45 mins) sometimes 4 depending on how long her naps have been. She's usually asleep for the night between 7:30-8:00

This is ours but I’m always on edge as feel it could change any day!
Up at about 7, nap at 9, nap at 12 and nap at 3. Roughly 45 mins on average. Times change if they are longer.
Bed at about half 6.
