Hello, my LO is 4 months orld now. It goes by so quickly! He started sleeping through the night (about 8 pm to 6 am) about 3 or 4 weeks ago. Then suddenly 2 days ago he started waking in the middle of the night again and wanting to nurse more frequently during the day. He also seems more fussy and irritable. I feel like he isn't getting as much milk when he is nursing because I don't hear him doing a lot of swallowing. I was wondering if it could be a growth spurt or if he may be teething. Does this all sound normal or could my supply be decreasing for some reason? Thank you all in advance for your support and advice. You all are lifesavers!
