Sleep problems 3 weeks old.

Kirsty🌹

So my son hit 3 weeks on Monday and he just does not sleep at night he’s having about 3-4 hours sleep overall during the night and sleeping mainly in the daytime. I’ve been up since 2am with him and it’s now 5:40am is anyone else’s baby doing this it’s becoming a regular thing where he stays up for hours during the night, it’s really not ideal as I have a 2 year old that will be up in an hour or so so I’ve got to function for the day after being up since 2am. 🤦🏼‍♀️
